Herein, the multimodal noncontact temperature readout approach based on GdP₅O₁₄ nanocrystals co-doped with Cr³⁺ and Nd³⁺ ions is reported. Each of the temperature readout Modes based on the: Stokes emission of Cr³⁺ and Nd³⁺(Mode I), Stokes and anti-Stokes emission (Mode II) and anti-Stokes emission (Mode III) of Nd³⁺ enables temperature determination in different spectral range providing the possibility to cross-checking readout verification. Independent optical addressing and the different performance to temperature sensing of the particular temperature readout mode enable development of versatile luminescent thermometer with enhanced temperature readout accuracy. The best performance for noncontact temperature sensing with the highest achieved relative sensitivity, wide usable temperature range and the δT ~ 0.15 °C reveals the Mode II based luminescent thermometer.

在此，报道了基于共掺杂有Cr ³⁺和Nd ³⁺离子的GdP ₅ O ₁₄纳米晶体的多峰非接触温度读出方法。每个基于读出的方式下的温度的：铬的斯托克斯发射³⁺和Nd ³⁺的Nd（模式I），斯托克斯和反斯托克斯发射（模式II）和反斯托克斯发射（模式III）³⁺可以确定不同光谱范围内的温度，从而可以交叉检查读数验证。独立的光学寻址以及特定温度读数模式对温度感测的不同性能，使得能够开发出具有更高温度读数精度的多功能发光温度计。非接触式温度感测的最佳性能，具有最高的相对灵敏度，较宽的可用温度范围和δT〜0.15°C，这说明了基于模式II的发光温度计。
