Key Points

Doping with trivalent Sb3+ ions significantly alters charge carrier recombination dynamics, enhancing PL stability.
The study demonstrates a clear relationship between ion doping and photoluminescence enhancement through changes in carrier dynamics.
Using systematic experimentation, the research differentiates effects on charge carriers due to the dopants introduced into the material.
These findings indicate the potential for improved photoluminescence in perovskite materials via focused ion doping strategies.

Implication

Doping with trivalent Sb3+ ions alters charge carrier dynamics in cesium lead bromide quantum dots, highlighting its impact on photoluminescence.

Abstract

Metal-ion doping of perovskites has proven to enhance their photoluminescence (PL) properties and stability; however, the underlying charge carrier dynamics remain unclear. We synthesized a cesium lead bromide (CsPbBr 3 ) perovskite...
