Thermoluminescence response and kinetic parameters of UV irradiated K3La(PO4)2:Pr3+ phosphor

Thermoluminescence (TL) response and kinetic parameters of Pr3+ doped K3La(PO4)2 phosphor under UV radiation synthesized by the combustion method had been reported. The X-ray diffraction pattern revealed a pure monoclinic phase of the K3La(PO4)2. The TL glow curves exhibited a single peak at ∼578±4 K. The TL intensity increased linearly upto 240 minutes of UV exposure. Further increase in the UV exposure time (dose) resulted into a decrease in the TL intensity. The values of the kinetic parameters obtained by the TLanal program were in good agreement with those obtained by the peak shape method. The present phosphor with a peak position at a higher temperature and the linear response upto 240 minutes of UV exposure, suggesting that the material may be suitable for its possible applications in UV dosimetry. But still more studies need to be done to explore the material in detail for dosimetric application.Thermoluminescence (TL) response and kinetic parameters of Pr3+ doped K3La(PO4)2 phosphor under UV radiation synthesized by the combustion method had been reported.
