Synthesis and characterization of red phosphor (Y,Gd)BO3:Eu by the coprecipitation method

The synthesis and luminescent properties of (Y,Gd)BO 3 :Eu phosphor were investigated. A coprecipitation method was designed for preparing Eu doped (Y,Gd)BO 3 . This method features a low-temperature formation of single phase with semi-spherical shape compared with the conventional method. Due to the homogeneous distribution of activator, the emission intensity of the (Y,Gd)BO 3 :Eu phosphor prepared by the coprecipitation method is higher than the commercially available red phosphor.
