Organometal halide perovskites have recently attracted tremendous attention due to their potential for photovoltaic applications, and they are also considered as promising materials in light emitting lasing devices. In this work, we investigated detail the cryogenic steady state photoluminescence properties of a prototypical hybrid perovskite CH3NH3PbI3-xClx. The evolution characteristics two excitonic peaks coincides with structural phase transition around 160 K. Our results further...
In this work, we explored perovskite oxide SrTiO3 (STO) for the first time as electron-transporting layer in organolead trihalide solar cells. The steady-state photoluminescence (PL) quenching and transient absorption experiments revealed efficient photoelectron transfer from CH3NH3PbI3–xClx to STO. Perovskite cells with meso-STO exhibit an open circuit voltage of 1.01 V, which is 25% higher than value 0.81 V achieved control device conventional meso-TiO2. addition, increase 17% fill factor...
We demonstrate that ultrathin P-type Cu2O thin films fabricated by a facile thermal oxidation method can serve as promising hole-transporting material in perovskite solar cells. Following two-step method, inorganic–organic hybrid cells were and power conversion efficiency of 11.0% was achieved. found the thickness properties layers must be precisely tuned order to achieve optimal cell performance. The good performance such attributed unique Cu2O, including high hole mobility, energy level...
We report an investigation of the impact surface passivation on optical properties ZnO nanorods. Al2O3 coating and hydrogen plasma treatment were used to passivate states. It was found that led suppression deep level emissions, while completely quenched emissions. confirmed states as-grown nanorod arrays indeed contributed Evidence also provided shows have a greater green emission than orange may cause negative thermal quenching behavior. Moreover, effect by changes O 1s Zn 2p spectra.
One method of obtaining the mass white dwarf in magnetic cataclysmic variables (mCVs) is through their hard X-ray spectra. However, previous estimates using this give lower limits because temperature plasma post-shock region (where X-rays are emitted) than shock itself. In AM Her systems, additional cooling by cyclotron emission will further derived mass. Here we present masses 13 mCVs Ginga data and a model which emitted from multi-temperature with appropriate density profile. We include...
The enhanced near band edge emission from a ZnO thin film and nanorod array by capping aluminum nanoparticles has been studied photoluminescence spectra. enhancement is attributed to the resonant coupling between bandgap transition of semiconductor surface plasmon metal nanoparticles. It also found that Al support deep-UV visible region with different annealing temperatures. This cost-effective approach useful for manufacturing highly efficient optoelectronic devices.
A controllable synthesis of various morphologies CuO nanostructures with tuning by hetero-metal cations has been developed in aqueous solution at room temperature. The can be engineered from nanosheets to nanoparticles different length ratios the long axis short axis. formation many metal–ion complexes plays an important role slowing release rate OH− and affects reaction kinetics further. We found that effect on final morphology was same as cooling series temperature-controlled experiments...
Ropivacaine for thoracoscopy-guided thoracic paravertebral block (TTPB) offers only a short duration of postoperative pain relief, which is inadequate managing following surgery. Research has shown that combining dexamethasone with ropivacaine significantly prolongs the analgesia from nerve block. We hypothesised TTPB combined would enhance and prolong in patients undergoing radical thoracoscopic lung cancer The study randomly assigned to either control group (Group C, n = 40) or D, 40)....
Dexmedetomidine is a central α-2 adrenergic agonist characterized by its sedative, analgesic, and sympatholytic properties. We investigated the effect of low dose dexmedetomidine on dose-response relationship propofol for sedation in patients undergoing operative hysteroscopy. The were firstly randomly assigned to receive either fentanyl (P group, n = 100) or combination propofol, dexmedetomidine, (DP 100). Subsequently, participants further randomized at doses 1.0, 1.5, 2.0, 2.5 mg/kg P...
Aluminium (Al) enhanced emission is investigated by temperature-dependent photoluminescence (PL) from ZnMgO films grown metal-organic chemical vapor deposition. The PL enhancement sensitive to both the thickness of Al film and temperature. ratio increases 3.5 ∼51 when temperature decreases room 20 K. Increased surface plasmon (SP) coupling decreased non-radiative recombination rate with decreasing are suggested account for giant enhancement. between excitons SP resonance confirmed time-resolved PL.
Nanostructured ZnO is considered to be a promising building block in the design of nanoscale optoelectronic devices. It usually shows dominant donor-bound exciton (DX) emission at low temperatures. In this study, nanorods with high crystallinity and optical quality were grown by metal–organic chemical vapor deposition on a-plane sapphire (110) substrates. Dominant free (FX) temperature (14 K) was observed photoluminescence spectroscopy. attributed both enhancement FX induced crystalline...
Abstract Persistent photoconductivity (PPC) is an intriguing physical phenomenon, where electric conduction retained after the termination of electromagnetic radiation, which makes it appealing for applications in a wide range optoelectronic devices. So far, PPC has been observed bulk materials and thin‐film structures, current flows plane, limiting magnitude effect.
