Recent Progress in the Development of Ce~(3+)-Activated Fluorosulfide and Fluorooxysulfide Phosphors for LED Lighting

摘要

Several novel fluorosulfide and fluorooxysulfide phosphors, Ce~(3+)-activated Y_2(Ca,Sr)F_4S_2, α- and β-YSF, and Y_3S_2OF_3 have been synthesizedand luminescence was investigated. Fluorosulfide-based phosphors can be excited by blue light and shows yellow-to-orange and red broadband emissions, respectively. Progress on the synthesis and luminescence of these phosphors is discussed.
