The environment-friendly synthesis and property modulation of two-dimensional organic-inorganic halide perovskite (2D OHP) single crystals with large sizes high quality are important for the fabrication optoelectric devices. In this work, plate-like centimeter-size (BA)2Pb(BrxI1-x)4 (BA = n-butylammonium, x: 0-1) crystallinity were synthesized via cooling crystallization method in a mixed HX (X: I, Br) acid aqueous solution. samples single-phase homogenously distributed Br I ions. lattice...
Novel and covert fluorescence is quite desirable for fluorescent anticounterfeiting application. Here, Cs2InCl5·H2O/Sb Cs2NaInCl6/Sb with high photoluminescence quantum yields (PLQYs) of 99.61 99.9%, respectively, were achieved. Considering the excellent optical performances together similarity two crystal structures, we tried to realize structure transition from by an ion-exchange method. It was well done just adding NaCl precursor different concentrations in product. Interestingly, a...
Measurement of the oxygen dissociation fraction in RF low pressure oxygen/argon plasma using optical emission spectrometry is presented. The and its evolutions as functions operational parameters were determined argon actinometer. At a 30 Pa, decreased from 13.4% to 9.5% input power increased 10 W 70 W. an 50 W, 12.3% 7.7% when gas Pa 40 Pa. influences on generation atomic also discussed.
Heterogeneous assembly of metal halide perovskites (MHPs) structures offers convenience for promoting the interfacial properties perovskite heterojunctions, which have been widely used in new generation photoelectric devices.
