Tailoring the Luminescence Properties of Cs_<b>2</b>TeCl_<b>6</b> Nanocrystals <i>via</i> High-Pressure and Low-Temperature Stimuli for Multiparameter Optical Manometry and Thermometry.

ABSTRACT: To search for a bifunctional luminescent platform for optical manometry and thermometry, Cs₂TeCl₆ nanocrystals were prepared. Excited at 456 nm, the designed nanocrystals emitted dazzling orange emission, whose fluorescence intensity, full width at half-maximum (fwhm), and decay time were sensitive to temperature. Through analyzing the temperature-dependent lifetime, the thermometric properties of the resulting nanocrystals were evaluated, resulting in a high relative sensitivity of 3.76% K^-1. The pressure-related Raman spectra demonstrated the splendid structural stability and reversibility of the studied samples. By studying the pressure-dependent Raman modes, one knows that the maximum pressure sensitivity of the Cs₂TeCl₆ nanocrysta
