Multi‐mode optical thermometry is emerging as a promising technique for accurate temperature measurement. Here, a series of Na2GdMg2V3O12:Sm3+ (NGMVO:xSm3+) phosphors with dual‐emission centers were successfully elaborated. Irradiated by 349 nm light, NGMVO:Sm3+ can generate emissions from VO43− and Sm3+ simultaneously due to energy transfer between them. Benefitting from difference of thermal quenching performance of two luminescent centers, fluorescence intensity (FI), fluorescence intensity ratio (FIR), and Commission Internationale de L'Eclairage coordinate modes of NGMVO:Sm3+ thermometer were designed. Maximum relative sensitivities (SR) are found to be as high as 2.21 %K−1, 2.12 %K−1, and 0.244 %K−1, respectively. Besides, with temperature increasing, SR values of FI and FIR modes decrease slowly. Their minimal SR values between 303 and 513 K maintain above 1.36 %K−1 and 1.08 %K−1, respectively. Our findings reveal that NGMVO:Sm3+ phosphors have promising applications for multimode temperature senor.

Inorganic chiral materials have attracted increasing attention due to their application prospects. In this work, we synthesized the chiral nanostructured bismuth oxychloride co‐doped with Er3+/Yb3+ phosphor (D‐BYEP) by hydrothermal growth with a subsequent air‐annealing strategy using chiral sugar alcohols as the chiral inducer. The D‐BYEP emitted bright red light under the excitation of 980 nm near‐infrared laser. The temperature sensing behavior was evaluated by employing the thermally coupled (TCLs) or non‐thermally coupled (NTCLs) levels of Er3+. The maximum relative sensitivities (SR) obtained are 0.84% K−1 and 1.30% K−1 (298 K), respectively. The results show that the D‐BYEP may be ideal candidates for optical temperature sensors. We anticipate that this new type of inorganic chiral phosphor may have a range of applications in temperature measurement of light sources.
