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

The synthesis and luminescent properties of (Y,Gd)BO₃:Eu phosphor were investigated. A coprecipitation method was designed for preparing Eu doped (Y,Gd)BO₃. 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)BO₃:Eu phosphor prepared by the coprecipitation method is higher than the commercially available red phosphor.
