Description |
Cerium dope CaS phosphor has been successfully prepared by solid state diffusion method. The phosphor is characterized by X-ray powder diffraction, transmission electron microscopy, selected area electron diffraction, thermogravimetric analysis and photoluminescence. Thermoluminescence and electron spin resonance studies also have been carried out on CaS:Ce phosphor. Irradiated CaS:Ce exhibits electron spin resonance (ESR) lines due to defect centres. The thermal annealing behaviour of one of the defect centres appears to correlate with the thermoluminescence (TL) peak at 135 degrees C. The centre is characterized by an isotropic g-value of 2.0036 and is assigned to a F+ centre. (c) 2006
