• Ca(S:Se) phosphors activated with Mn were synthesized bu making use of pure CaS and CaSe powders prepared carefully by chemical procedures. X-ray inspection showed that Vegard's relation is valid in Ca(S:Se) system. Spectral distribution of emission band, excitation spectra and electron spin resonance were measured about these phosphors. Racah parameters of Mn^<2+> ion and crystal field parameter Dq are determined by an analysis of observed excitation peaks. The most fitted value of 10Dq for these phosphors lies between 6100 and 6500cm^<-1>. The absolute value of their fine structure coupling constant lies between 70 and 77×10^<-4>cm^<-1>, being nearly independent of CaSe content. The comparison between the values of these two parameters of Ca(S:Se):Mn phosphors and those of Zn(S:Se):Mn phosphors, reported in the previous paper, shows that the Mn^<2+>-anion bond in the formers contains far less covalency than in the latters.
