This study pioneers a novel strategy for synthesizing solar-blind ultraviolet (UV) nonlinear optical (NLO) crystals through functional groups sequential construction, effectively addressing the inherent trade-offs among broad transmittance, enhanced second-harmonic generation (SHG), and optimal birefringence. We have developed two innovative van der Waals layered germanous phosphites: GeHPO

World hunger is getting worse, while one-third of foods produced around the globe wasted and never consumed. It vital in reducing food waste to promote sustainability agri-food systems. Intelligent packaging embedded with freshness indicators can monitor a real-time manner be deployed for cutting due predetermined expiration date informing consumers safety. Biodegradable halochromic films have been increasingly utilized as because their low environmental impact. In this review, recent...

Birefringent crystals are extensively utilized across diverse optical applications due to their unique property of splitting incident light into dual refracted rays, thereby modulating and controlling polarization. The pursuit promoting the birefringence such facilitate device miniaturization has recently emerged as a prominent area focus. In this investigation, we introduce two molybdenyl iodates, namely, C(NH2)3MoO3(IO3) Rb2MoO2(I2O6)(IO3)2, conceived through "cation–anion synergetic...
