Abstract
⺠High luminescence (La,Gd)Sr2(Al,B)O5:Ce yellow phosphor was prepared for LED application. ⺠Luminescence properties were optimized by changing the content of Gd and B substituent. ⺠A red shift in the emission was observed by the substitution of Gd3+ and B3+ ions. ⺠The red shift was due to the lattice shrinking for Gd3+ and the increase of lattice covalency for B3+. ⺠The optimized sample had about 368% improved emission intensity compared with LSA:Ce.
