Ultrastability and color-tunability of CsPb(Br/I)3 nanocrystals in P–Si–Zn glass for white LEDs†
Abstract
A series of CsPbBrxI3−x NC glasses, showing tunable emission (523–693 nm) controlled by different ratios of Br− and I−, were successfully prepared. The CsPbBrxI3−x NC glasses exhibited excellent optical properties and outstanding stability towards ambient conditions, water and heat.
