The results manifest that the phase purity of Ce³⁺/Eu²⁺/Sm³⁺ co-doped SMYP phosphors was verified by the Rietveld structure refinements. Under 315 nm ultraviolet (UV) excitation, the Ce³⁺ single-doped SMYP phosphor reveals a broad and strong bluish-violet emission band in the range of 325–480 nm. The outstanding enhancement of Eu²⁺ emission intensity is realized by Ce³⁺ induced resonance energy transfer (ET). The ET mechanism of Ce³⁺→Eu²⁺ is governed by an electronic quadrupole-quadrupole interaction with a high ET efficiency of 89.8 %. In addition, the luminescent color of SMYP: Ce³⁺/Eu²⁺ samples can be changed from light green to white by introducing activators Sm³⁺ ions. The optimal chromaticity coordinate could be adjusted to (0.311, 0.343), which is the closest to the ideal white light coordinate (0.330, 0.330). To achieve white light, a white LED device fabricated by combining a 310 nm chip with the SMYP: Ce³⁺/Eu²⁺/Sm³⁺ phosphor shows a high color rendering index (CRI = 87.2) along with a low correlated color temperature (CCT≈4056.7 K) under the stimulation of 5 V voltage and 100 mA current.

A series of NP samples with varying Y/Er molar ratios were synthesized to identify the optimal composition for incorporation into optical fibers.

In this study, we researched the contamination process of high-reflectivity multilayer HfO₂/SiO₂ film components, simulated the process of stray light irradiation on stainless steel components, inducing damage and particulate sputtering through experimentation, and then conducted characterization and damage performance tests on the contaminated samples. When stainless steel is irradiated with low energy density (≥10 mJ/cm²) stray light, it produces non-metallic particulate contaminants that affect the components' damage performance. The higher the laser energy density, the more complex the process of generating particulate contaminants and the more severe the impact on damage performance.
