Abstract
We studied the necessary preparation temperature to draw full potential of SrS:Ce luminescence. To improve the crystallization and luminescence efficiency of SrS:Ce phosphor layers, post-deposition annealing at high temperature is necessary. Firing SrS powders above 1000℃ introduces Sr vacancies into the SrS lattice. In the presence of many Sr vacancies, many Ce^<3+> centers are incorporated into the SrS lattice. By adding alkali metal sulfide, it is possible to show high luminescence of SrS:Ce powders for firing temperatures below 1000℃. Alkali metal sulfide co-evaporation may have the potential to reduce the optimum deposition temperature of SrS:Ce thin films.
