Summary: CaMoO4:Pr3+ thermochromic phosphors with diverse thermal responses were prepared by the solid-phase reaction method. The CaMoO4:Pr3+ phosphor had a scheelite structure and good thermal stability at 605 nm emission peak but poor thermal stability at 490 nm. The relative sensitivity of the CaMoO4:Pr3+ phosphor was better than most phosphors, indicating its potential for optical thermometry applications.

Summary: SrMoO4: Sm3+ phosphors with orange red-emitting properties were synthesized using a solid-phase method for temperature measurement applications. The phosphors had a scheelite structure belonging to the tetragonal system and I41/a space group. Sm3+ ions were successfully incorporated into the SrMoO4 lattice. The phosphors exhibited irregular microparticles with well-crystallized pomegranate seed-like morphology, and Sm3+ ions were evenly distributed in the SrMoO4 matrix. The appropriate quenching concentration of Sm3+ was found to be 1.0%, and the phosphors showed excellent thermal stability and anti-thermal quenching properties. A new dual-model thermometry strategy based on exponential function and modified Boltzmann population distribution was proposed, and the phosphors demonstrated absolute sensitivities of 0.108 K-1 and relative sensitivities of 0.601% K-1. The findings highlight the potential applications of SrMoO4: Sm3+ phosphors in pc-WLEDs and optical thermometry.

Summary: The optical thermometry performance of europium (Eu3+) doped Y7O6F9 phosphors was studied by analyzing the fluorescence temporal and spectral change with temperature. The choice of host material was found to greatly impact the temperature sensitivity, and Yttrium oxyfluoride was identified as a suitable candidate due to its low phonon energy and high chemical and thermal stability. The fluorescence spectral profile of the phosphor changed when exposed to a controlled change in temperature, and the phosphor demonstrated a temperature sensitivity of 0.08% K-1 and 0.35% K-1 using different methods.

Summary: The luminescence of Eu3+ doped calcium magnesium silicate (CMS: Eu3+) phosphor was experimentally studied by optimizing the single diopside structure in the solid state reaction method and theoretically verified using first principle density functional theory (DFT) calculation. The results showed that a transition from agglomerated morphology to particle formation occurred at 900 degrees C, and a combination of diopside and akermanite structures were formed at 800 degrees C, while a single diopside phase was optimized from 900 degrees C onwards. The stability and site preference of Eu3+ ion in CMS were determined through DFT calculation, indicating that Eu3+ replacing Ca lattice position had the minimum mixing energy.

Summary: Regulating the chemical components is an effective approach to develop rare earth doped phosphors with excellent luminescent performances. In this study, the photoluminescence and mixed valences of Eu2+/3+ in Sr2(Al, Ga)2SiO7 can be adjusted by regulating Ga3+. The site-dependent luminescence of Eu2+ in Sr2(Al, Ga)2SiO7 is discussed based on VUV-UV-vis spectra. Ab initio calculation and simulation of X-ray photoelectron spectra (XPS) reveal that the increase ratio of Eu3+ to Eu2+ is mainly attributed to the decrease of band gap and fermi level. As a result, the emission color of Sr2(Al, Ga)2SiO7: Eu2+/3+ can be tuned by different replaced Ga3+ contents, wavelengths, and temperatures. Temperature-dependent measurements indicate that the Eu2+/Eu3+ ratiometric emission can sensitively indicate the temperature variation under excitation at 300 nm. After fine modification by Ga3+, Sr1.9Eu0.1Al1.9Ga0.1SiO7 phosphor shows a sensitive temperature readout.
