To obtain the divalent Eu emission from phosphate phosphor which is important for phosphor applications, heat treatments under reducing atmosphere at high temperature are required usually. We have found that the divalent emission can be also obtained by laser irradiation. In this study, the reduction processes in KSr1-xBaxPO4:Eu alloy system have been examined and constructed an optical reduction scheme in order to clarify the difference between the chemical and optical reduction processes.
