Description
Summary:For producing new luminescent materials, we take phosphor material CaYAl3O7 with varying concentration of transition metal Mn2+ synthesized by combustion method at 500°C. The synthesized phosphor material characterized for their crystallinity and nature by XRD measurements. The thermoluminescecne response of phosphor exhibit TL spectra at 188°C and detailed analysis of kinetic parameter by de convoluted curve. The parameters show that the order of kinetics is second, also the concentration increase results in the decreased activation energy and frequency factor. We can conclude that the present system of Mn doped phosphor is suitable and compatible for industrial applications such as dosimetry, Scintillation and solid state devices.
