Naturally, endogenous porphyrins can provide sensitized disinfection power, and to photobiologists' delight, violet-blue light has potential virtues, but progress is needed before violet-blue light treatment can be used for microbe treatment of blood plasma, and yet safeguard against protein photooxidation. A report by Maclean et al. in this issue of Photochemistry & Photobiology on microbe reduction in blood plasma showing negligible competing protein photooxidation may bring that goal a step closer.

Low-dimensional lead-free metal halide perovskites are highly attractive for cutting-edge optoelectronic applications. Herein, we report a class of scandium-based double perovskite crystals comprising antimony dopants that can generate multiexcitonic emissions in the ultraviolet, blue, and yellow spectral regions. Owing to the zero-dimensional nature of the crystal lattice that minimizes energy crosstalk, different excitonic states in the crystals can be selectively excited by ultraviolet light, X-ray irradiation, and mechanical action, enabling dynamic control of steady/transient-state spectral features by modulating the excitation modes.

Added safety measures coupled with the development and use of pathogen reduction technologies (PRT) significantly reduces the risk of transfusion-transmitted infections (TTIs) from blood products. Current approved PRTs utilize chemical and/or UV-light based inactivation methods. While the effectiveness of these PRTs in reducing pathogens are well documented, these can cause tolerable yet unintended consequences on the quality and efficacy of the transfusion products.

YSiO:Ce, YSiO:Dy, and YSiO:Ce and Dy phosphors were successfully synthesized using the oxalate wet chemical method. Phase purity, emission and excitation spectra, FTIR, and the chromaticity coordinate were adopted to represent the performance of the samples. The photoluminescence (PL) spectrum YSiO:Ce and Dy phosphor shows a broadband in violet-blue region with a bandwidth of nearly 75 nm due to combine effect of Ce-Dy ions with another emission peaks of Dy ions peaking at 574 nm.

The razor clam , a commercially important and nutritionally valuable bivalve species, has been found to display notable responses to different light spectra. While previous research has highlighted the influence of light spectra on the growth, feeding rate, and various physiological characteristics of , its impact on the biochemical composition of this species remains unclear. Herein, we investigated the proximate, fatty acid, and amino acid compositions of cultured under various light spectra, including white, violet, blue, cyan, green, yellow, red, and darkness.
