N2 - Temperature sensing in the cryogenic range is highly demanded in many advanced scientific applications and technologies. Luminescence thermometry provides remote temperature reading via the monitoring the chosen optical parameter. However, to widen the usage of luminescence thermometers, their performances should be improved. Here, multiparameteric luminescence thermometry using multiple linear regression was proposed and compared with conventional single-parameter sensing. Thermal studies were performed with ZnTe epitaxial layers with submonolayer CdTe inclusions, which allows providing temperature monitoring within 20–100 K. Simultaneous use of LIR, spectral position and bandwidth results in more than 10 times increase of relative sensitivity compared with conventional single-parameter thermometry. Thus, the unprecedently high Sr = 60 % K−1@25K was obtained via multiparametric thermal sensing, which makes such strategy perspective for further improvement of thermometric performances.
