Ultrastable germanium oxide induced self-crystallization of CsPbBr3@glass for white light-emitting devices and wide color gamut backlight displays

Abstract

The GeO₂ additive has a ‘network breaking’ effect on the network structure of silicate glass, which promotes the in situ nucleation/growth of PNCs in the glass. This effect is beneficial for reducing surface defects, and the prepared CsPbBr₃@glass has a PLQY of up to 90%.
