Synthesis QDs

I synthesized quantum dots by the cheap method. The synthesized quantum dots are GQDs and CdTe. The PL of quantum dots has always been investigated in my research. 

Quantum dots (QDs) are artificial nanoscale crystals that can transport electrons. When UV light hits these semiconducting nanoparticles, they can emit light of various colors. These artificial semiconductor nanoparticles have found applications in composites, solar cells, and fluorescent biological labels.
