Abstrakt: Results are presented from testing the temperature of a two-phosphor composite ([Ru(dipy)3]2+@SiO2 and NaYF4:Eu, Gd) in order to determine the prospects for its application as a luminescent thermal sensor in the range of 200–310 K. By calibrating the temperature dependences of individual spectral components of emissions produced upon irradiation with a cw laser at 405 nm, the possibilities of temperature sensing by means of ratiometric method are analyzed in four different spectral ranges of the composite's visible luminescence.
