Abstract
The Sr2.93B2O6:0.07Eu2+ yellow phosphor samples were synthesized by a rapid microwave heating method. The structure, luminescent properties and the effects on structure and luminescence of heating temperature were studied through a systematic research. The excitation and emission spectra indicate that this phosphor can be effectively excited by blue light of 460nm, and exhibit bright yellow emission peaking at 555nm. The main excitation peak is at 468nm, which is very suitable for blue chip excitation. The structure of Sr2.93B2O6:0.07Eu2+ phosphor is a hexagonal system with a R*c(167) space group.
The high pure phase Sr2.93B2O6:0.07Eu2+ phosphor can be obtained at 1150 by a microwave heating method. Similarly, the
heating temperature of optimum luminescent phosphor is also at 1150..
