With Mn-doping, ZnSnanostructures exhibit a strong photoluminescence. The LEDs exhibit electroluminescence(EL) from Mn-doped ZnSquantum dots and TPD. In order to open up channels for energy-transfer from TPD to quantum dots and to achieve EL from only the nanoparticles, we grow core-shell nanoparticles with Mn-doped ZnS in the core and CdS as the shell layer. Excitons formed in TPD can now transfer their energy directly to the shell-layer to yield EL from only the nanoparticles.</p>1 aRath, Arup, Kumar1 aBhaumik, Saikat1 aPal, Amlan, J.  uhttps://library.ncl.res.in/content/mn-doped-nanocrystals-light-emitting-diodes-energy-transfer-obtain-electroluminescence
