Article Abstract
The development of novel phosphor materials with excellent performance and modification of their photoluminescence to meet the higher requirements for applications are the essential research subjects for luminescent materials. Multi-site luminescent materials with crystallographic sites for the activator ions that broaden the tunable range of luminescent spectra and even enhance the luminescent performance have attracted significant attention in the pursuit of high-quality luminescence for white light-emitting diodes. Here, we summarize multi-site luminescence characteristics based on the different kinds of host and activator ions, introduce the identifications of multi-site activator ions via optical analysis, provide a structural analysis and theoretical calculation methods, and introduce the regulation strategies and advance applications of multi-site phosphors. The review reveals the relationship between crystal structure and luminescent properties and discusses future opportunities for multi-site phosphors. This will provide guidance for the design and development of luminescent materials or other materials science.

Organic high-temperature photothermal materials (T > 100 °C) have demonstrated significant application values because of their ability to exceed the temperature limits of traditional organic photothermal materials, enabling spatiotemporally controllable long-distance heating and high-temperature conversion of laser or sunlight. In this review, we summarize the recent progress in organic high-temperature photothermal materials, mainly including organic small molecule and polymer materials. Their photothermal conversion mechanisms and the factors influencing their performance as well as their applications, including photo controlled ignition/deflagration, photothermal induced actuators, photo controlled metal processing, and concentrated sunlight energy conversion were elaborated.

AlN is a core material widely used as a substrate and heat sink in various electronic and optoelectronic devices. Introducing luminescent properties into intrinsic AIN opens new opportunities for next-generation intelligent sensors, self-powered displays, and wearable electronics. In this study, the first evidence is presented of AlN crystals exhibiting satisfactory mechanoluminescence (ML), photoluminescence (PL), and afterglow performance, demonstrating their potential as novel multifunctional optical sensors.

Antibacterial photodynamic therapy offers a promising approach for combating both susceptible and multidrug-resistant pathogens. However, conventional photosensitizers have limitations in terms of poor binding specificity and weak penetration for pathogens. In this study, we developed synergistic photobactericidal polymers that integrate hydrophilic toluidine blue O (TBO) with the lipophilic penetration enhancer citronellol (CT).

Perovskites have a large number of intrinsic defects and interface defects, which often lead to non-radiative recombination, and thus affect the efficiency of perovskite solar cells (PSCs). Introducing appropriate passivators between the perovskite layer and the transport layer for defect modification is crucial for improving the performance of PSCs. Herein, two positional isomers, 1-naphthylmethylammonium iodide (NMAI) and 2-naphthylmethylammonium iodide (NYAI) are designed.
