Formation of pristine PbBi2Se4 and rGO-PbBi2Se4 composite were confirmed by X-ray diffraction and X-ray photoelectron spectroscopy. The surface morphology and topography investigated by using scanning electron microscopy and transmission electron microscopy revealed the formation of nano-flowers pristine PbBi2Se4. After coupling pristine PbBi2Se4 with rGO the surface morphology shows the formation of sharp vertically protruded nano-sheets/nano-flaks originated from the nano-flowers. Finally, the field emission properties of pristine PbBi2Se4 and rGO-PbBi2Se4 composite have been investigated. It has been observed that the rGO-PbBi2Se4 composite emitter exhibited excellent field emission properties with low turn-on field (similar to 2.8 V/A mu m for 10 A mu A/cm(2)), high emission current density (similar to 1288 A mu A/cm(2) at 3.9 V/A mu m) and superior current stability (similar to 4.5 h for similar to 1 A mu A) compare to pristine PbBi2Se4 emitter. Thus, the facile one step synthesis approach and robust nature of rGO-PbBi2Se4 composite emitter can provide prospects for the future development of large-area emitter applications such as flat-panel-display and vacuum micro/nanoelectronics devices.</style></abstract><issue><style face="normal" font="default" size="100%">12</style></issue><work-type><style face="normal" font="default" size="100%">Article</style></work-type><custom3><style face="normal" font="default" size="100%">Foreign</style></custom3><custom4><style face="normal" font="default" size="100%">2.325</style></custom4></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Pandharkar, Subhash</style></author><author><style face="normal" font="default" size="100%">Rondiya, Sachin</style></author><author><style face="normal" font="default" size="100%">Bhorde, Ajinkya</style></author><author><style face="normal" font="default" size="100%">Nair, Shruthi</style></author><author><style face="normal" font="default" size="100%">Aher, Rahul</style></author><author><style face="normal" font="default" size="100%">Vairale, Priti</style></author><author><style face="normal" font="default" size="100%">Waghmare, Ashish</style></author><author><style face="normal" font="default" size="100%">Naik, Dhirsing</style></author><author><style face="normal" font="default" size="100%">Waykar, Ravindra</style></author><author><style face="normal" font="default" size="100%">Jadhav, Yogesh</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Probing the effect of selenium substitution in kesterite-Cu2ZnSnS4 nanocrystals prepared by hot injection method</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of Materials Science-Materials in Electronics </style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2019</style></year><pub-dates><date><style  face="normal" font="default" size="100%">AUG</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">30</style></volume><pages><style face="normal" font="default" size="100%">14781-14790</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;&lt;span class=&quot;hitHilite&quot;&gt;In&lt;/span&gt; this paper, we report &lt;span class=&quot;hitHilite&quot;&gt;the&lt;/span&gt; &lt;span class=&quot;hitHilite&quot;&gt;effect&lt;/span&gt; &lt;span class=&quot;hitHilite&quot;&gt;of&lt;/span&gt; sulfur (S) &lt;span class=&quot;hitHilite&quot;&gt;substitution&lt;/span&gt; &lt;span class=&quot;hitHilite&quot;&gt;with&lt;/span&gt; &lt;span class=&quot;hitHilite&quot;&gt;selenium&lt;/span&gt; (Se) &lt;span class=&quot;hitHilite&quot;&gt;in&lt;/span&gt; CZTS &lt;span class=&quot;hitHilite&quot;&gt;nanocrystals&lt;/span&gt; &lt;span class=&quot;hitHilite&quot;&gt;prepared&lt;/span&gt; &lt;span class=&quot;hitHilite&quot;&gt;by&lt;/span&gt; &lt;span class=&quot;hitHilite&quot;&gt;hot&lt;/span&gt; &lt;span class=&quot;hitHilite&quot;&gt;injection&lt;/span&gt; &lt;span class=&quot;hitHilite&quot;&gt;method&lt;/span&gt;. &lt;span class=&quot;hitHilite&quot;&gt;The&lt;/span&gt; formation &lt;span class=&quot;hitHilite&quot;&gt;of&lt;/span&gt; kesterite-&lt;span class=&quot;hitHilite&quot;&gt;copper&lt;/span&gt; zinc tin sulfide (Cu2ZnSnS4, CZTS) and &lt;span class=&quot;hitHilite&quot;&gt;copper&lt;/span&gt; zinc tin selenide (Cu2ZnSnSe4, CZTSe) &lt;span class=&quot;hitHilite&quot;&gt;nanocrystals&lt;/span&gt; is confirmed &lt;span class=&quot;hitHilite&quot;&gt;by&lt;/span&gt; X-ray diffraction (XRD), Raman spectroscopy and transmission electron microscopy (TEM) analysis. &lt;span class=&quot;hitHilite&quot;&gt;The&lt;/span&gt; XRD, TEM and atomic force microscopy (AFM) analysis shows an overall increase &lt;span class=&quot;hitHilite&quot;&gt;in&lt;/span&gt; average crystallite size upon Se &lt;span class=&quot;hitHilite&quot;&gt;substitution&lt;/span&gt;.

Humidity sensor and photodetector based on PbBi2Se4 nano-flowers are fabricated on indium tin oxide (ITO) substrates and their sensing properties are investigated. Formation of PbBi2Se4 is confirmed by XRD, EDS, and XPS whereas formation of nano-flowers is confirmed by SEM and TEM analysis. XRD analysis reveals the hexagonal crystal structure of PbBi2Se4 phase with a = b = 4.22 angstrom, and c= 17.42 angstrom. The surface morphology of PbBi2Se4 clearly shows the formation of well-organized flower-like nanostructures which closely resembles the shape of Dahlia. The elemental mapping of chemical constituents obtained from SEM-EDS analysis shows uniform distribution of chemical constituents for the Pb, Bi, and Se in PbBi2Se4 nano-flowers. The PbBi2Se4 nano-flowers based humidity sensor has a typical response time of approximate to 65s and recovery time of approximate to 75 s. In case of PbBi2Se4 nano-flowers-based photodetector, the response and recovery time are observed approximate to 121 and approximate to 123 s, respectively, under visible light illumination with photoresponsivity (5 x 10(-6)), photosensitivity (2.16%), and quantum efficiency (1.5 x 10(4)). The obtained results demonstrate the potential applications of solvothermally grown PbBi2Se4 nano-flowers-based devices for humidity sensors and photodetectors. The ease of the present work is to develop novel material to obtain device quality humidity sensors and photodetectors.&lt;/p&gt;
