Luminescence Properties and Spectral Control of Ba3Ce1-xK(PO4)3F:xTb3+ Phosphor
phosphors were prepared by high temperature solid state method. Their structure

phosphor gradually changes from blue light to blue green light and finally to green light as the Tb

ions can strongly sensitize the luminescence of Tb
