| Abstract: |
This study synthesized LaF3–LaOF:Yb3+/Ho3+via a solid-state reaction method and analyzed its optical properties and temperature sensitivity. Specifically, the crystalline structure of each sample—composed of LaOF (tetragonal) and LaF3 (hexagonal)—were analyzed under X-ray diffraction. In addition, their photoluminescence (PL) properties were analyzed, with peaks observed at 543, 654, and 755 nm. The highest PL intensity was observed at 543 nm for a molar ratio of La:Yb:Ho = 1:0.05:0.001. Furthermore, the temperature characteristics of each sample were analyzed to determine the absolute and relative sensitivities as 0.0232 K−1 and 0.357 %K−1, respectively. [ABSTRACT FROM AUTHOR] |
