Аннотация: Doping or alloying in perovskites and perovskite variants provides a promising way for modulating the electronic and photoluminescence properties and the structural stability. In this work, a series of yellow-emitting Rb2-xCsxZrCl6:Te4+ solid solution phosphors were prepared by a hydrothermal method, and their broad emission is assПоказать полностьюigned to the triplet 3P1-1S0 self-trapped excitons (STEs). Upon increasing the alloying ion Cs+, the yellow emission can be greatly enhanced by a stronger Jahn-Teller distortion. Moreover, Cs2ZrCl6:Te4+ shows a high photoluminescence quantum yield (PLQY), and impressive thermal and anti-water stability. This doping-alloying strategy presents a new direction towards designing lead-free, high-performance and stable perovskite derivatives. This journal is © the Partner Organisations.
