Investigation of nanophosphor of SrSO4 activated by Sm and Tb as a potential UV detector
In this research, nanocrystalline powder of SrSO4: Sm was prepared by chemical co-precipitation method at room temperature. The SrSO4: Sm nanocrystalline powder was characterized using X-ray diffraction (XRD) and energy-dispersive x-ray spectroscopy (EDX), thermoluminescence (TL) and photoluminescen...

| description | In this research, nanocrystalline powder of SrSO4: Sm was prepared by chemical co-precipitation method at room temperature. The SrSO4: Sm nanocrystalline powder was characterized using X-ray diffraction (XRD) and energy-dispersive x-ray spectroscopy (EDX), thermoluminescence (TL) and photoluminescence (PL). Under UV irradiation, all samples had a main peak at 220˚C. The advantage of this nanocrystalline powder is a simple TL glow peak in the temperature above 200˚C for UV radiation dosimetric. The results showed that changing Sm concentration affected the TL glow curve intensity and the maximum intensity of the TL glow curve of SrSO4: Sm was obtained for Sm with 0.15 mol%. The TL response of the SrSO4: Smirradiated with different UV irradiation time showed a linear behavior from 10-90 minutes. The fading of this nanocrystalline powder was less than 16% for 4 weeks. Moreover, the emission spectra of the SrSO4: Smnanocrystalline powder under excitation wavelength 320 nm showed peaks in the 690 and 725 nm wavelengths which were related to 4G5/2-6H11/2 and 4G5/2-6H13/2, respectively. |
