Comparative Analysis of Spectral Broadening Techniques for Optical Temperature Sensing in Yttrium Fluoride (YF<sub>3</sub>) Doped with Neodymium

Comparative Analysis of Spectral Broadening Techniques for Optical Temperature Sensing in Yttrium Fluoride (YF<sub>3</sub>) Doped with Neodymium

In this work, YF<sub>3</sub>:Nd<sup>3+</sup> powder was synthesized using the microwave-assisted hydrothermal method at a low temperature (140 °C) and short synthesis time (1 h). The photoluminescence and optical temperature sensing properties of YF<sub>3</sub>:Nd...
