The GQDs are well confined due to the adsorption on the growing face of the ZIF-8 nanocrystals and have a profound effect on the shape of the nanocrystals from rhombic dodecahedron to spherical. Stabilizing GQDs inside the ZIF-8 nanocrystals results in tailoring of the photoluminescence emission (ca. 32 nm, bathochromic shift) of the GQD@ZIF-8 nanocrystal composite even after 3 months of aging under normal laboratory conditions. Also the water adsorption (at STP) capacity increased for the GQD@ ZIF-8 composite as compared to the pristine ZIF-8.</p>1 aBiswal, Bishnu, P.1 aShinde, Dhanraj, B.1 aPillai, Vijayamohanan, K.1 aBanerjee, Rahul  uhttps://library.ncl.res.in/content/stabilization-graphene-quantum-dots-gqds-encapsulation-inside-zeolitic-imidazolate-0
