Description

Inorganic perovskite quantum dots (IPQD) are semiconductor nanoparticles with high color tunability, making them optimal materials for optoelectronic devices. Current CsPbBr3 IPQDs have high quantum yields (QY) and broad absorption and emission profiles, but are limited in commercial implementation due to the toxicity of lead. This poster will discuss the synthesis of silica-coated manganese-substituted Cs(Pb/Mn)Br3 IPQDs. Replacing lead with manganese reduces the toxicity of the nanoparticles while maintaining the high QY, and the addition of a silica shell improves the stability of the IPQD. These modifications produce higher quality nanoparticles with broadened applications in optoelectronic devices.
