Thermoluminescence study of Eu3+ doped Na2Sr2Al2PO4Cl9 phosphor via doping of singly, doubly and triply ionized ions

Enhanced photoluminescence in RE (Eu3+, Ce3+ and Sm3+)‐activated Ca10(PO4)F2 phosphors by double or triple ionized mineral doping: a comparative study

“…Figures 29 and 30 show the CIE chromaticity diagrams of rare‐earth‐activated Ca 10 (PO 4 ) 6 F 2 phosphor following doping with VO 4 3− , WO 4 2− , or SO 4 2− ions. [ 48 ] PL was not observed when SO 4 2− was replaced by PO 4 3− for Eu 3+ and also not observed for Sm 3+ on replacement of VO 4 3− ions. When doping with WO 4 2− ions, intensity was enhanced for both rare earths.…”

Investigation of thermoluminescence response and trapping parameters of natural barite samples from Dongargaon mine, India

“…Chen’s peak shape method, [ 38,39 ] the repeated initial rise (RIR) method, [ 40,41 ] and Ilich’s method. [ 42,43 ]…”

“…The formula for calculation of activation energy using Ilich’s method is given in Kadam et al . [ 43 ] According to this formula, 15% of glow curve data are used to calculate activation energy. Initial glow curves used to calculate activation energy are displayed in Figure 13; Table 6 summarizes the trapping parameters calculated using Ilich’s method.…”

Tailoring of thermoluminescent properties and assessment of trapping parameters of natural fluorite samples from Dogargaon fluorite mines, India

“…The different dose rate study shows the maximum intensity of the irradiated phosphor at 456 Gy observed at a peak centered at 200 C as displayed in Figure 6 which is useful in dosimetric properties. [22][23][24][25] Moreover, the TL glow curve intensity has been increasing linearly with increasing exposure rate. The linearity of the dose response exposure was determined by the slope of the linear fitted curve.…”
