Low-Yellowing Phosphor-in-Glass for High-Power Chip-on-board White LEDs by Optimizing a Low-Melting Sn-P-F-O Glass Matrix

Low-Yellowing Phosphor-in-Glass for High-Power Chip-on-board White LEDs by Optimizing a Low-Melting Sn-P-F-O Glass Matrix

Abstract We introduce a low-melting-point (MP) Sn-P-F-O glass ceramic material into the phosphor-in-glass (PIG) material to realize an ‘on-chip’ chip-on-board (COB) type of phosphor-converted (pc) white light-emitting diode (WLED) with green (BaSr)2SiO4:Eu2+ and red (SrCa)AlSiN3:Eu2+ (SCASN) phospho...
