## Description

- description: "Non-contract optical thermometry shows great advantages for temperature
    measurement in harsh environments, and it is highly desired to develop novel and
    high-performance systems. In this work, a novel K3(Y0.88Yb0.10Er0.02)Si2O7 phosphor
    was synthesized via solid-state reaction, and its up-conversion luminescence and
    optical thermometric performance were systematically investigated. Under 980 nm
    \r\nexcitation, the K3(Y0.88Yb0.10Er0.02)Si2O7 phosphor showed a strong green
    UC emission through a three photon process. The phosphor was found well capable
    of sensing temperature via the multi-modes of fluorescence intensity ratio (FIR)
    of thermally/non-thermally coupled energy levels and fluorescence lifetime (FL).
    The maximum absolute (SA) and relative (SR) sensitivities are SA = 156×10-4 K
    -1 (I531/I555, 298 K) and SR = 1.80% K-1 (I519/I555, 298 K) via the FIR mode,
    and are SA = 661×10-4 K-1 (548 K) and SR = 9.77% K-1 (298 K) via the FL mode,
    which are higher than those of most previous studies."
