AN OPTIMAL METHOD FOR SYNTHESIS OF QUALITY XS PHOSPHOR HOST MATERIALS

Properly-doped alkaline-earth sulfides (AES:Ds) are a promising group of versatile phosphor materials for many important optronic and photonic devices, such as HDTV, full-color TFEL panels, and optical information processing elements, etc. One of the key issues to successful practical applications of AES:Ds is to first grow quality XS (X= Ca, Sr, etc) base materials. This paper proposes a new method for preparing XS with which CaS and SrS were successfully synthesized. The also given is a study on the reaction efficiency of the new technique; the phase purity, chemical and crystallographic characteristics of the materials tailored with the new method. The experimental results indicate that the newly-developed preparing method is more advantageous over the currently widely used method.
