Chemically tuned organic–inorganic hybrid halide perovskites based on bromide and chloride anions CH(NH2)2Pb(Br1−xClx)3 (CH(NH2)2+: formamidinium ion, FA) have been crystallized investigated by neutron powder diffraction (NPD), single crystal X-ray (SCXRD), scanning electron microscopy (SEM) UV–vis spectroscopy. FAPbBr3 FAPbCl3 experience successive phase transitions upon cooling, lowering the symmetry from cubic to orthorhombic phases; however, these are not observed for mixed phases, probably due compositional disorder. The band-gap engineering brought about chemical doping of FAPb (Br1-xClx)3 (x = 0.0, 0.33, 0.5, 0.66 1.0) can be controllably tuned: gap progressively increases with concentration Cl− ions 2.17 2.91 eV at room temperature, presenting a nonlinear behavior. This study provides an improved understanding structural optical properties appealing perovskites.

Single-Crystal Diamond Nanowires Embedded with Platinum Nanoparticles for High-Temperature Solar-Blind Photodetector

Nano-Micro Letters, Год журнала: 2025, Номер 17(1)

Опубликована: Апрель 16, 2025

Abstract Diamond, an ultrawide-bandgap semiconductor material, is promising for solar-blind ultraviolet photodetectors in extreme environments. However, when exposed to high-temperature conditions, diamond photodetector surfaces are unavoidably terminated with oxygen, leading low photoresponsivity. To address this limitation, single-crystalline nanowires (DNWs) embedded platinum (Pt) nanoparticles were developed using Pt film deposition followed by chemical vapor (CVD) homoepitaxial growth. During the CVD, (approximately 20 nm diameter) undergo dewetting and become uniformly within DNWs. Photodetectors fabricated these nanoparticles-embedded DNWs achieve a responsivity of 68.5 A W −1 under 220 illumination at room temperature, representing improvement approximately 2000 times compared oxygen-terminated bulk devices. Notably, further increases reaching exceptional value 3098.7 275 °C. This outstanding performance attributed synergistic effects one-dimensional nanowire structure, deep-level defects, localized surface plasmon resonance induced nanoparticles, Schottky junctions Pt/diamond interface, which enhance optical absorption, carrier generation, separation efficiency. These results highlight significant potential advanced deep detection harsh environments, including aerospace, industrial monitoring, other applications.
