A high-performance ultra-narrow-band green-emitting phosphor LaMgAl 11 O 19 :0.28Mn 2+ ( λ em = 517 nm, FWHM ∼24 nm) is prepared by a solid-state reaction in air, which can be applied pc-wLED with wide color-gamut value of 131% NTSC and 97.8% Rec. 2020.
Abstract Developing fluorescent materials that can achieve efficient upconversion (UC) emission under low power density excitation has always been a great challenge, especially for Tm 3+ ions. Here, ‐doped Cs 2 NaYbCl 6 double perovskite single‐crystals (DPSCs) are prepared successfully. The DPSCs exhibit UC 980‐nm laser excitation, and the optimum efficiency reaches 9.48%. It is recorded value. More importantly, its be achieved low‐power of 0.117 W cm −2 excitation. Moreover, luminescence...
Based on dual-emission centers with a compact distance, broad-scope optical thermometer high sensitivity and temperature resolution is designed.
Cesium lead halide perovskite (CsPbX3, X = Cl, Br, and I) nanocrystals (NCs) have attracted enormous attention because of their great potential for optoelectronic applications, such as light-emitting diodes (LEDs). However, the photoluminescence surface ligands CsPbX3 NCs a impact on device applications. Herein, we report molecular superacid bis(trifluoromethane)sulfonimide (TFSI), which could boost in metal nanocrystals. In particular, quantum yield (PLQY) CsPbI3 be greatly improved from...
Halide perovskites (HPs) are highly susceptible to heat, light, or moisture and easily decomposed even in an ambient environment, which greatly hinders their practical applications. Herein, situ growth strategy is presented for implanting inorganic lead-free HP, Cs2AgBiBr6, into SiO2 sub-microcapsules form a Cs2AgBiBr6@SiO2 yolk-shell composite. The sub-microcapsule endows Cs2AgBiBr6 with good thermal light stability, as well excellent corrosion resistance against polar solvents....
Motivated by the growing demand for noncontact temperature sensing in cryogenic environments, development of a high performance low optical thermometer has become more and urgent. Herein, we demonstrate new broadband emitting bismuth singly activated Ba2ZnSc(BO3)3 thermometric material that exhibits remarkable temperature-dependent emission color variation good performance. First, Bi3+ doped phosphors were successfully synthesized high-temperature solid-state reaction. Upon excitation at 320...
Oxide-free silicon surfaces were obtained using a high-vacuum wafer-bonding system by bombarding wafer with argon ions. Wafers subsequently bonded after the ion treatment. Both single wafers and characterized. The results of ions energies varying over one order magnitude (from factor 0.5 to 5 baseline energy E0) are presented in this study. It is found that resulting damage layer thickness increases increasing but density ion-energy independent, which was about 80% bulk crystalline density....
Abstract The conventional hydrogen production process is accompanied by the of large amounts carbon dioxide, which affects application energy. Therefore, it necessary to monitor dioxide content gas. Due their excellent optical properties, all-inorganic perovskites can be made into photoluminescence sensors for monitoring gas concentrations. However, toxic lead halide are limited in photoelectric applications due instability and other drawbacks. Perovskites have rarely been studied broadband...

The incidence of androgenetic alopecia in males is on the rise annually, with hair transplantation using follicular unit extraction (FUE) gaining increasing acceptance as an appropriate treatment for these individuals. A retrospective study was undertaken, involving 158 male patients diagnosed alopecia, who underwent between January 2016 and December 2020 at Medical Cosmetology Department First Affiliated Hospital Xi'an University. Demographic data characteristics were documented analyzed....
