Description
Mehri Ghasemi, Qi Li, Baohua Jia, and Xiaoming Wen probe how a perovskite crystal glows under light in a 2026 study. The glow often grows faster than a simple rule would predict, and the power in that rule shifts with the light used. Static models that sort glow into fixed channels do not always explain the pattern.
Tests on thin films varied light strength, timing, and the history of light exposure. Glow scaling, delayed glow, and past light effects moved together as conditions changed how the crystal sheds shaking energy. The authors read the superlinear glow as a result of linked charge and lattice cooling, and they warn that glow measures are not fixed traits of the material.
