Abstract
Luminescent materials and methods of forming such materials are described herein. A method of forming a luminescent material includes: (1) providing a source of A and X, wherein A is selected from at least one of elements of Group 1, and X is selected from at least one of elements of Group 17; (2) providing a source of B, wherein B is selected from at least one of elements of Group 14; (3) subjecting the source of A and X and the source of B to vacuum deposition to form a precursor layer over a substrate; (4) forming an encapsulation layer over the precursor layer to form an assembly of layers; and (5) heating the assembly of layers to a temperature Theat to form a luminescent material within the precursor layer.
