In the recent years due to their various optical and technological applications fluoride materials have attracted attention of several researchers. When these materials are doped with rare earth ions they show properties favorable for many optical applications such as high quantum efficiencies. The perovskite type fluorides of formula ABF{sub 3} where A= Alkali earth metal (Li,Na,K,Rb,Cs) and B= Alkaline earth metal (Mg,Ca,Ba,Sr) are of special interest to the research workers because of their wide range of applications that includes these materials as thermoluminescence detector, laser material, scintillator, X-ray imaging and storage phosphor, quantum cutter for VUV applications etc. Due to the high symmetry and technological efficiency of the growth process these crystals are good model objects for fundamental studies and in some cases they are of great practical value. This paper reports photoluminescence properties of UV emitting KMgF{sub 3}, NaMgF{sub 3} and LiBaF{sub 3} phosphors prepared by reactive atomospheric process. X-ray diffraction and photoluminescence characteristics of these phosphors are also mentioned.
