Abstract We discuss the influence of Al3+ on the charge transfer state (CTS) and the photoluminescence roperties of BaZr(BO3)2:Eu. The results reveal that there is a red shift which is about 20nm for the charge transfer state when doping with Al3+ and indicate the formation of `free’ electrons due to the change of microstructures. In addition, the influence of Al3+ doping on the PPR is analysed and a new explanation is raised based on the photo luminescent mechanism. It is the CTS intensity rather than the CTS energy that influences the peak-peak ratio.
