The calculated results indicate that the 3d states of Mn have donor energy level in the forbidden band of CdMoO4 crystal. The O^2- transition energy of O 2p→Mn 3d is 3.12eV under excitation corresponding electronic transition being O^2-+Mn^2+→↑hvex=3.12 eV O^-- +Mn^+→↑hvem O^2-+Mn^2+. It is predicted that the wavelength of emission should be located in the range of the 500-600nm. Thus the 500-600mm emission bands peaking at 550nm (2.25eV) of CdMoO4 crystal under excitation may be related to the Mn-like dopant ion in CdMoO4 crystal. %K 61 %K 72 %K Ji %K 61 %K 72 %K Bb %K 71 %K 15 %K -m %K 71 %K 20 %K -b
