Summary: A series of SrGa12-xAlxO19:0.5%Cr3+(x = 0, 2, 4, and 6) solid-solution phosphors were successfully synthesized through Al3+ alloying strategy. The introduction of Al3+ can regulate the crystal field and symmetry, achieving the synchronous tuning of E-2 and T-4(2) energy levels and extending the temperature sensing range. Among all samples, SrGa6Al6O19:0.5%Cr3+ showed the widest temperature measuring range from 130 K to 423 K with Sa of 0.0066 K-1 and Sr of 1% K-1@130 K. This work provides a feasible way to extend the temperature sensing range for transition metal-doped LIR-mode thermometers.

Summary: Researchers have discovered a new phenomenon of excitation-wavelength-dependent anti-thermal quenching (anti-TQ) luminescence in the Eu3+-doped Sc2Mo3O12 phosphor. This luminescence shows intensified energy transfer from the host to the dopant and increased intensity at elevated temperatures, particularly when excited at 277 nm. The mechanism behind this anti-TQ luminescence is attributed to the negative thermal expansion property of the Sc2Mo3O12 host. The findings provide inspiration for the development of thermally enhanced phosphors with intensified energy transfer for various applications.

Summary: In this work, controlled energy transfer was achieved by suppressing the host to dopant energy transfer in La2Hf2O7:Eu3+ nanoparticles through co-doping with uranium ions. The co-doping creates negatively charged vacancies in the system to compensate for the excess charge in U and Eu co-doped La2Hf2O7 NPs, suppressing the formation of oxygen vacancies. This study demonstrates the potential for producing near perfect white light emission by utilizing the full color gamut in La2Hf2O7:Eu3+,U6+ nanoparticles.
