Summary: The optimal doping content of co-doped phosphors was directly obtained through simulation using the response surface methodology (RSM) method. In this study, the optimal sample (OPT-SYNO) of Sr2YNbO6:Bi3+,Eu3+ phosphors was predicted using RSM. The structure and luminescent properties of Sr2YNbO6:Bi3+,Eu3+ phosphors were examined through X-ray diffraction and photoluminescence. The temperature-dependent emission spectra of OPT-SYNO showed that it can achieve dual-mode optical thermometry (fluorescence intensity ratio and color coordinate) under different excitations. Under 338 nm excitation, the maximum values of SR and SA were 0.898 %K-1 (453 K) and 4.285 %KK (-1) (573 K), respectively. These results indicate the potential application of Sr2YNbO6:Bi3+,Eu3+ in optical temperature measurement.

Summary: Fluorescence temperature measurement technology has sparked a new wave of non-contact temperature measurement, but the single-mode thermometry still has a large error. In this study, a dual-mode modulation thermometry based on GaNbO4:Yb3+/Er3+ up-conversion phosphor is achieved in a wide temperature range of 93-633 K, with a maximum relative sensitivity of 11.7% K-1 (93 K) and 13.1% K-1 (123 K). The GaNbO4:Yb3+/Er3+ phosphors were synthesized using the high temperature solid-state method and characterized for their structure, surface morphology, and optical properties. The fluorescence intensity ratio (FIR) readout method based on Er3+ thermal-coupled and non-thermal-coupled energy levels was used for the dual-mode temperature measurement. The results demonstrate the great potential of GaNbO4:Yb3+/Er3+ phosphors in high sensitivity broadband thermometry.

Summary: A series of CLMV:Sm3+ phosphors were synthesized as new optical temperature sensing materials, and their structures, morphologies, and luminescent properties were investigated. The energy transfer from VO(4)(3-)to Sm(3+) was demonstrated, and a three-mode optical temperature sensor was designed based on the temperature dependent emission and excitation characteristics of VO(4)(3-) and Sm(3+). The sensing modes included the fluorescence intensity ratio (FIR) of I(Sm3+) and I(VO43-), Commission International de L'Eclairage (CIE) coordinate, and the excitation intensity ratio (EIR) of I-383nm/I-405nm. The CLMV:Sm3+ phosphors showed high absolute and relative sensitivities in FIR and EIR modes, indicating their potential as self-referencing optical thermometers.

Summary: Site engineering is an important modulation strategy for adjusting the physicochemical properties of lanthanide luminescent ions. This study explores the influence of changing M2+ (or RE3+) ions on the occupation preference of Pr3+ ions and related crystal-field splittings. The results show that Pr3+ ions possess different doping sites in different materials, and replacing M2+ ions has a significant impact on the energy-level splitting. Additionally, the materials demonstrate excellent temperature sensing performance based on defect and Site II emissions.

Summary: A novel temperature-sensitive material, Sr3Y2Ge3O12:Bi3+,Sm3+ phosphor, was synthesized successfully by a solid-state reaction method. Under 376 nm light excitation, the prepared phosphor exhibits blue emissions from Bi3+ and orange red emissions from Sm3+ due to energy transfer. The temperature sensing performance of the phosphor was evaluated by measuring the fluorescence intensity ratio (FIR) of Sm(3+)versus Bi3+. Moreover, it was found that the sensitivities of Sr3Y2Ge3O12:Bi3+,Sm3+ could be tuned by changing the concentration of activators to determine the optimal temperature measurement conditions.

Summary: In this study, first-principles calculations were used to investigate the luminescence properties of four different ternary oxide materials, namely (Sr/Ca)Sb2O6, (Sr/Ca)2Sb2O7, (Sr/Ca)SnO3, and (Sr/Ca)Ga2O4, doped with bismuth ions. The effects of bismuth doping on the materials' luminescence properties were analyzed by studying intrinsic defects and self-trapped holes. The transitions associated with bismuth ions in different materials were also identified. The insights gained from this study are important for understanding the luminescence mechanisms of insulating bismuth-doped ternary oxides.

Summary: The study proposes an internal self-regulation anti-thermal quenching strategy to develop Pr3+-activated GdNbO4 red phosphor, which can compensate for the loss of red emission intensity during heating by utilizing a metal-to-metal charge transfer mechanism between Pr3+ ions and Nb5+ ions. This approach enables the phosphor to maintain or even enhance its integrated photoluminescence intensity from 300 K to 620 K, showing promise for high-temperature applications and optical temperature sensing.
