Abstract Mixed‐halide perovskites are promising materials for optoelectronic applications due to their tunable bandgaps and high photoluminescence quantum yields. However, these face challenges such as phase segregation under excitation instability when exposed polar solvents, especially in blue‐emitting regions. In this study, a facile mechanochemical synthesis method is developed produce CsPb(Br x Cl 1‐x ) 3 ‐ MOF (Metal‐organic framework) glass composites. By precisely controlling the halide composition optimizing milling conditions, composites containing quantum‐confined perovskite particles with significantly improved stability, (PL), solvent resistance achieved. Notably, composite can maintain up 77% PL efficiency after soaking water year. Structural optical analyses revealed that process fosters interfacial bonding between glass, effectively regulating particle size passivating surface defects. To demonstrate practical applications, violet blue light‐emitting diode (LED) devices fabricated, achieving CIE color coordinates of (0.152, 0.031) (0.134, 0.045), respectively. This work offers scalable, eco‐friendly approach synthesizing stable, high‐performance perovskites, paving way integration into next‐generation devices.

Mercury and explosives are well-known hazards that affect the environment threaten society. generally exists as inorganic mercuric (Hg2+) salts, its detection via fluorometric response is highly notable. Likewise, mainstream contains a nitro (−NO2) moiety functional unit, numerous reports have quantified them using fluorescence quenching. Among available literature, there still noticeable concerns about environmental biological applicability of luminescent pyrene derivaives-tunedfluorometric Hg2+ explosives. In presence ions, derivatives tend to form excimers, which can be tuned chelation-enhanced (CHEF), photo-induced electron transfer (PET), or resonance energy (FRET), etc., exhibit “Turn-On” “Turn-Off” responses. On other hand, π-π stacking emissive pyrene-derivatives may lead J- H-type aggregation self-excimers (Py-Py*), has been found quenched/enhanced by explosive hazards. fact, −NO2-containing interact with derivatives, leading exceptional quenching enhancement. This review details use toward sensing demonstrated applications. Further, design requirements, sensory mechanisms, advantages, limitations, future scope reported in discussed.

Embedded sensor technologies have emerged as pivotal tools in redefining structural health monitoring (SHM) within composite materials, addressing a critical need the structure industry. Composites, by their layered nature, are particularly vulnerable to internal delamination and micro-cracks from impacts, which can propagate lead catastrophic failures. Traditional inspection methods often fail detect damage these undetected damages reduced performance potential system sensors offer solution capable of detecting spectrum damages, barely visible impact (BVID) subtle low-energy impacts pronounced impact-related deformations, all real-time. Key sensors, such Piezoelectric transducers (PZTs), Fiber Bragg Gratings (FBGs), other been discussed detection techniques this review. This review discusses comprehensive picture progress current scenario different embedded for SHM structures. The growth technologies, limitations, future requirements focusing on materials Finally, challenges opportunities development sustainable paper.

Abstract Advancing the development of luminescent nanoprobes and conjugates toward toxic analyte quantification plays a crucial role in environmental remedy. Cyanide ions (CN − ) play vital many industries, such as electroplating, mining, textiles, metallurgy, etc. The highly CN may be discharged into environment. presence aquatic environment at micromolar level could lead to fatal issue humans living beings, which requires scrutiny maintain ecosystem. Thus, diverse probes, organic fluorophores, noble metal nanoparticles/clusters (NPs/NCs), carbon/graphene quantum dots (CQDs/GQDs), cadmium telluride/selenide (CdTe QDs/CdSe QDs), cadmium/zinc/silver sulfide (CdS QDs/ZnS QDs/ Ag 2 S etc, were proposed with real-time applications. Among them, probes/conjugates derived from QDs, NPs, NCs are unique display astonishing selectivity sensitivity . observed responses can attributed agglomeration, inner filter effect (IFE), fluorescence resonance energy transfer (FRET), chemiluminescence (CRET), etc Till now there is no review article reporting applications for quantification. In this review, employment these detecting illustrated detailed underlying mechanisms Furthermore, design requirements, advantages, limitations, directions delivered future studies.
