Electrochemical doping was used to dope lithium into perovskite CsPbBr3 crystal. Due to the doping, diamagnetic behavior was observed with a transition temperature (Tc) of 7.17 K. Burstein–Moss effect related photoluminescence (PL) blue-shift was observed as long as 15 nm. UV–vis-NIR spectra indicate that the absorption has been enhanced. The doped CsPbBr3 crystal generated 8 nA photocurrent, which is higher than the undoped CsPbBr3 crystal.

锂掺杂钙钛矿型CsPbBr 3晶体的电化学锂掺杂引起的性能变化
使用电化学掺杂将锂掺杂到钙钛矿CsPbBr 3晶体中。由于掺杂，在7.17 K的转变温度（T c）处观察到抗磁性行为。观察到与Burstein-Moss效应相关的光致发光（PL）蓝移的时间长达15 nm。UV-vis-NIR光谱表明吸收得到了增强。掺杂的CsPbBr 3晶体产生8 nA的光电流，该电流高于未掺杂的CsPbBr 3晶体。
