Mini-light-emitting diodes (mini-LEDs) are regarded as a promising light source for future high-end electronic products. Phosphors with a small size and high efficiency have been reported to achieve this goal. Here, we demonstrate that an easily synthesized Ga 2 O 3 :Cr 3+ -embedded mesoporous silica nanoparticle (GOC@ MSN) is an outstanding nanophosphor with a superb internal quantum efficiency (91.4%) and a good thermal stability. Structural studies have determined the mesostructure and intermolecular transfer of free electrons. Meanwhile, spectral studies have demonstrated detailed luminescent and thermal properties. A mini-LED package using a GOC@MSN nanophosphor and covering 650−900 nm exhibits its potential for practical applications. This work provides insight into the space-limited ship-in-a-bottle synthesis method for achieving a high quantum efficiency in nanosized phosphors and motivates further research on luminescent materials that use mini-LEDs.

“…In terms of spectral properties, strengthening the coordination of metal nodes with organic linkers could enhance photo‐physical behavior. [ 43‐44 ] This is because the restricted coordination suppresses non‐radiative energy decay. [ 45 ] As is well known, the organic ligand is directly related to the absorption edge of MOFs.…”

“…[119][120][121][122][123] The unique structural characteristics and functionalities of the MOFs have also been advantageously used to craft protective layers for the HPPs. [124] In 2018, Su and co-workers reportedly used Zn-and Co-based zeolitic imidazolate frameworks (e.g., Zn-ZIF-8 and Co-ZIF-67) to encapsulate CsPbBr 3 QDs, and these encapsulated QDs were used as the HPPs for CO 2 reduction to CO and CH 4 in a CO 2 / water vapor reaction media. [125] Their core-shell structured CsPbBr 3 @Zn-ZIF-8 and CsPbBr 3 @Co-ZIF-67 HPPs exhibited noticeably improved humidity stabilities.…”

Solar‐energy‐powered photocatalytic fuel production and chemical synthesis are widely recognized as viable technological solutions for a sustainable energy future. However, the requirement of high‐performance photocatalysts is a major bottleneck. Halide perovskites, a category of diversified semiconductor materials with suitable energy‐band‐enabled high‐light‐utilization efficiencies, exceptionally long charge‐carrier‐diffusion‐length‐facilitated charge transport, and readily tailorable compositional, structural, and morphological properties, have emerged as a new class of photocatalysts for efficient hydrogen evolution, CO2 reduction, and various organic synthesis reactions. Despite the noticeable progress, the development of high‐performance halide perovskite photocatalysts (HPPs) is still hindered by several key challenges: the strong ionic nature and high hydrolysis tendency induce instability and an unsatisfactory activity due to the need for a coactive component to realize redox processes. Herein, the recently developed advanced strategies to enhance the stability and photocatalytic activity of HPPs are comprehensively reviewed. The widely applicable stability enhancement strategies are first articulated, and the activity improvement strategies for fuel production and chemical synthesis are then explored. Finally, the challenges and future perspectives associated with the application of HPPs in efficient production of fuels and value‐added chemicals are presented, indicating the irreplaceable role of the HPPs in the field of photocatalysis.
