Abstract Visible light microlasers are essential building blocks for integrated photonics. However, achieving low-threshold (μW), continuous-wave (CW) visible lasing at room temperature (RT) has been a challenge because of the formidable requirement population inversion short wavelengths. Rare-earth (RE)-activated microcavities, featuring high-quality factor ( Q ) and small mode volume whispering gallery modes, offer great opportunity infrared-to-visible upconversion (UC) lasing. Here, we...
Abstract The toxicity of heavy‐metal Pb and instability lead‐based halide perovskite nanomaterials are main factors to impede their practical applications in the fields solar cells, LEDs scintillators. In this paper, all inorganic lead‐free cesium manganese nanocrystals synthesized glass for first time. Red photoluminescence with broad PL band, negligible self‐absorption a high quantum yield 41.8% is obtained. addition, modulating component can change Mn 2+ ions coordination environment...
Abstract High‐density scintillator glasses offer significant promise for advanced X‐ray imaging, particularly in X‐CT and compact detection systems. In this study, a series of Sn 2+ ‐doped gadolinium‐based (SBGA:xSn ) is synthesized, which exhibit densities ≈6 g cm −3 . These demonstrate broad emission bands ranging from 330 to 670 nm, with maximum photoluminescence quantum yield 75.1% shortest decay time 11 µs. Owing the high density substantial Gd 3+ content, absorption coefficient...
We report here a synthesis method for single-crystal monodisperse GeO2 nanocubes in reverse micelle system. Hydrolysis of germanium tetrachloride (GeCl4) system produces the presence oleylamine and cetyltrimethylammonium (CTAB). The average edge length cubes varies from 50 to 520 nm depending on concentration CTAB solution. perfection monodispersity are greatly improved by decreasing pH value water Different morphologies such as capsules can be prepared using octane oil phase. BFDH...
All-inorganic cesium lead halide perovskite quantum dots (PQDs) appear to be promising scintillators for radiation detection; however, they are suffering from poor stabilities against light, heat, and moisture. Here a strategy of using AgCl as the nucleating agent is developed facilitate growth <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"> <mml:mrow class="MJX-TeXAtom-ORD"> <mml:msub> <mml:mi mathvariant="normal">C</mml:mi> mathvariant="normal">s</mml:mi>...
A cuprous hybrid halide with high efficient photoluminescence and anti-water stability was prepared by reasonably selecting a hydrophobic organic cation, which allows this as high-performance scintillator for X-ray imaging.
Abstract Mn 2+ ‐activated metal halides are widely reported in multi‐functional optoelectronic applications. However, ‐related optical thermometry is seldom discussed.
