In this paper we have synthesized powder crystal form (Y,Gd) BO₃:Eu³⁺phosphors by microwave heating method.Its structure belongs to hexagonal system with lattice parameters a=0.3796,c=0.8835.Its excitation spectra peaks at 239.0nm and 240.0nm monitored at the emission of 589nm and 612nm respectively,the half peak width is 40nm.Under 240nm excitation the phosphors show a strong orange-red luminescence,the fluorescent intensity ratio for I₅₈₉/I₆₁₂ is 1.9/1
