The calcium magnesium silicate (CaMgSi 2 O 6 ) phosphor activated with the trivalent/divalent rare-earth ions R 3? /R 2? (R 3? /R 2? = Ce 3? ; Sm 3? ; Eu 3? ; Eu 2? ; Dy 3? and Tb 3? ) ions were synthesized by the solid state reaction method. The crystal structure and luminescence properties were investigated by X-ray diffraction and photoluminescence analysis in detail. The crystal structures of sintered phosphors were monoclinic structure with space group C2/ c. The excitation spectra of CaMgSi 2 O 6 :R 3? /R 2? indicated that all samples could be effectively excited by near UV light. Emission spectra of the samples have emitted strong violet-blue, orange-red, blue, near white light and green light, due to the characteristic transitions of Ce 3? ; Sm 3? ; Eu 3? ; Eu 2? ; Dy 3? and Tb 3? respectively. Thus, based on the favorable photoluminescence properties under the near UV light excitation, these phosphors could be nicely suitable for the white light emitting diodes.

In the present investigation dysprosium doped strontium aluminate phosphor was prepared by combustion synthesis method. The crystal structure of the prepared phosphor was consistent with standard monoclinic phase with a space group P2 1 . According to the TEM analysis, the particle size was found to be in the nanometer range. The trap parameters which are mainly activation energy (E), frequency factor (s) and order of the kinetics (b) were evaluated by using the peak shape method. Under the ultraviolet (365 nm) excitation, photoluminescence (PL) spectra showed characteristic emission bands at 480 (blue), 573 (yellow) and 670 nm (red) due to 4
