Polyvinylpyrrolidone-assisted aqueous synthesis of monodisperse CH3NH3PbBr3 perovskite nanocrystals
Metal halide perovskites are difficult to be prepared entirely in water due to their ionic nature. Aqueous synthesis routes of methylammonium lead bromide (CH3NH3PbBr3) perovskite were reported previously, but th...

SnSe nanoparticles with the ultra-low lattice thermal conductivity: synthesis and characterization
Tin selenide (SnSe) with an orthorhombic system has recently become a hot spot in the thermoelectric field owing to its low thermal conductivity and high melting point. In this work, P-type SnSe nanoparticles ...

Clean waveguides in lithium niobate thin film formed by He ion implantation
We report on the fabrication of channel waveguides by He ion implantation in a single-crystal LiNbO3 film bonded to a SiO2/LiNbO3 substrate. The planar waveguides were also formed under the same conditions to sho...

Studies of recombination X-ray-laser gain and gain-medium uniformity
The time evolution of the uniformity of the line-shaped X-ray-laser gain medium and the spatial characteristics of the recombination X-ray-laser gains of the Li-like ions are studied using long (∼900 ps) and s...
