Thermoluminescence glow curve analysis of Ca3Y2B4O12 phosphor prepared using combustion method

Ca3Y2B4O12 (CBYO) phosphor was synthesized using a gel combustion method. X-ray diffraction (XRD) measurement confirmed a single-phase structure (space group Pnma (62)) of synthesized compound. TL measurements were conducted between room temperature (RT) and 450 degrees C at a heating rate of 2 degrees Cs-1. Significant glow peaks were observed at 64, 116, and 242 degrees C in CYBO phosphor sample exposed to different beta doses. In the range of 0.1-100 Gy, the TL intensity of the glow peak displayed good linearity. Different methods were employed to determine the number of peaks, the trap structure, and the kinetic parameters of the thermoluminescence glow curve of CBYO; the Hoogenstraaten method, various heating rates (VHR), and glow curve deconvolution method (CGCD) implemented through tgcd:An R package. Currently available findings confirm that CYBO host is a promising candidate for environmental studies because one exhibits adequate TL dose response coupled with a good sensitivity and linearity.

Automated summary

In this study, the CBYO phosphor was successfully synthesized using a gel combustion method, and XRD measurement confirmed its single-phase structure. TL measurements revealed significant glow peaks at different beta doses, showing good linearity in the range of 0.1-100 Gy. Multiple methods were used to determine the number of peaks, the trap structure, and the kinetic parameters of the CBYO phosphor. The findings suggest that CBYO is a promising material for environmental studies due to its adequate TL dose response, sensitivity, and linearity.
