In this work, the problem has been tried to resolve by preparing Ba2ZnSi2O7: Dy3+phosphor. X-ray diffraction shows their structure as monoclinic which was further confirmed by Rietveld refinement techniques. Optical studies have been done to confirm their luminescence properties. Stimulated at 351 nm, the as-prepared phosphors show blue (469 nm) and yellow (577 nm) emissions. The 4F9/2 ➔ 6HJ (J = 13/2, 15/2) transitions of Dy3+ ions are responsible for these emissions, and they were also utilized to optimize the dopant concentration. The latter has two types of fluorescence intensity ratios and a type of excitation intensity ratio with maximum relative sensitivities of 2.05% K−1 and 1.96% K−1, respectively. Using an optimized phosphor, which exhibits good optical temperature measuring capabilities, a temperature measurement model was constructed using the fluorescence lifetime (FLT), with a maximum value of SR = 5.42% K−1.

These materials can be synthesized using various combinations of divalent and trivalent metal cations. Herein, we investigate the synthesis and photoluminescence (PL) properties of Mg (Al, Tb)-LDHs with different incorporated interlayer anions, specifically carbonate (CO32−) and chloride (Cl−). The CO32−-incorporated Mg (Al, Tb)-LDH was synthesized using a hydrothermal method, whereas Cl− was introduced through anion exchange.

The CO32−-incorporated Mg (Al, Tb)-LDH was significantly more photoluminescent than its Cl− counterpart. However, further analysis using electron spin resonance and X-ray absorption fine structure techniques revealed that the Tb3+ electronic state is unaffected by the anionic species. Synchrotron radiation X-ray diffractometry and subsequent Rietveld analysis revealed that thermal fluctuations of the anionic species and hydrated water in the interlayer space are the primary factors that influence PL intensity.
