Summary: This research presents the successful formation of ZnSe/amino functionalized graphene quantum dots (af-GQDs) with type-II core-shell structures. The structures show potential as a single emissive layer and exhibit tunable photoluminescence emission in the visible region. The introduction of functional groups on af-GQDs enhances their properties and reduces Auger recombination. The study also investigates the emission properties of ZnSe/af-GQDs through steady state and temperature dependent photoluminescence spectroscopy, as well as characterizes the structure using X-ray photon spectroscopy measurements. The findings suggest that ZnSe/af-GQDs have great potential for LEDs and display devices.

Summary: The highly sensitive afterglow intensity ratio (AIR) thermometry based on thermal quenching (TQ) mechanism using Y3Al2Ga3O12:Pr3+ persistent phosphor is reported. The AIR shows strong temperature dependence in the range of 30-170 degrees C, with a maximum relative sensitivity of up to 4.12% degrees C-1 at 170 degrees C. The method is demonstrated by accurately measuring water temperature with an error of only 0.1 degrees C.

Summary: This study investigated the luminescence properties and temperature sensing performance of Sm3+ and Mn4+ co-activated LaGaO3 phosphors, revealing their dependency on ambient temperature and optical behavior at different temperatures. The anti-thermal quenching performance of Sm3+ ions and emission declination of Mn4+ ions were observed, leading to a recorded temperature sensitivity of 4.19% K-1 and 2.09% K-1 based on the fluorescent intensity ratio (orange/red) of the phosphor. The explored film combined with LaGaO3: Sm3+, Mn4+ phosphor showed potential as a multi-color optical thermometer.

Summary: This article investigates the influence of doping Sm3+ ions in the Ba3Zr2O7 host lattice. Ba3(1-x)Zr2Sm3xO7 samples with different Sm3+ concentrations were prepared using a solution combustion route. XRD and XPS techniques were employed to study the structure and chemical compositions of the phosphor. The results showed that Sm3+ doping significantly affected the luminescence spectra of Ba3Zr2O7 phosphor, making it a promising candidate for amber gap filling in LEDs.

Summary: The photoluminescence characteristics of Eu3+ ions help investigate the distribution of hazardous radioactive Am3+ ions, indicating a preference for Am3+ ions to occupy the Ca2 site with a direct linkage to F atom. Experimental and theoretical observations suggest doping Am3+ ions into the Ca2 site is preferable for radioactive waste immobilization. Additionally, the Eu3+ doped compound exhibits red color emission with a high color purity of 95.24%.
