摘要	This paper studied the preparation of CaS powders by sulfurizing CaCO3 in different atmosphere such as S+N-2, S+air, H2S+H-2, H2S, S+H2S and S+H2S+H-2 with different reactive methods. The formation of impurity phases such as CaSO4 and CaO depends strongly on the sulfurizing atmospheres. The amount of F+ vacancies and the influence of F+ vacancies on the blue luminescence of CaS:TmF3 phosphor were studied by photoluminescent (PL) and photoluminescent excitation spectra (PLE). It is concluded that CaS powders containing large amount of F+ vacancies are not suitable for preparation of efficient CaS:TmF3 phosphor because of the energy transfer from host and Tm3+ luminescent centers to the F+ vacancies. The qualified CaS powder for CaS:TmF3 phosphor was prepared by sulfurizing CaCO3 in S+H2S atmosphere.
