Summary: Golgi stress is a major stress response in the Golgi apparatus that may disrupt redox balance and be related to various diseases. Hydrogen peroxide (H2O2), an important reactive oxygen species, plays a crucial role in the Golgi apparatus and abnormal concentrations of H2O2 can cause oxidative damage. On the other hand, hydrogen sulfide (H2S) acts as a protective agent to alleviate Golgi stress. A Golgi-targeted fluorescent probe, Golnap-H2O2, has been developed as a specific imaging tool for detecting H2O2 in the Golgi apparatus and as a potential H2S donor for cytoprotection.

Summary: In this study, Eu-doped YVO4 single crystals with different concentrations were fabricated to evaluate their photoluminescence and scintillation properties. The results showed that the samples doped with Eu exhibited emission peaks due to 4f-4f transitions in PL and scintillation spectra. Based on the pulse height spectra, the light yield of the Eu-doped samples increased with increasing Eu concentration, while the afterglow level decreased.

Summary: This study successfully prepared phosphor samples based on Ca3-xLuxSc2-xMgxSi3O12:Ce3+ and investigated their luminescence properties. With the increase in Lu-Mg concentration, the peak of the sample redshifted, but the thermal stability gradually decreased. The LD devices made from CLSMS:Ce3+ fluorescent materials showed a decrease in cyan-green light and an increase in red light as the Lu-Mg concentration increased.
