Abstract:
We have reported low toxic essential amino acids as bidentate ligand for synthesis of
MAPbBr3 perovskite nanocrystals with excellent optical properties. This investigation
shows that mechanochemical method is preferred over conventional colloidal
chemistry during synthesis. To better understand the optoelectronic property, different
amino acids have been studied and compared. All morphological and optical studies
are performed to characterize the synthesized perovskite nanoparticles. Later, stability
studies are investigated through Thermogravimetric analysis, temperature dependent
PL, time dependent XRD as well XPS studies. Interestingly, these perovskites show
high luminescence upon scratching on flexible conducting plates and on plain paper
surface. This investigation demonstrates the importance of generating high quality
fluorescent nanoparticle for photonic applications including light emitting diodes and
imaging.
