Room-Temperature Synthesis of Cesium Lead Halide Perovskite Nanorods
Low-dimensional materials attract much attention because of their unique and outstanding properties in optical and electronic products,giving a promising class of materials for optoelectronic applications.A facile synthesis method of CsPbBr3 nanorods(NRs)was presented in this paper.The nanorods have a one-dimensional(1D)scale,a high photoluminescence quantum yield(PLQY,60%)and a narrow FWHM.By tuning the ratio of organic ligands,the CsPbBr3 NRs with the diameter of less than 20 nm and length up to several hundred nanometers were obtained.Moreover,because of the quantum confinement effects,a large blue-shift have happened in PL spectra.A light-emitting diode(LED)device was fabricated with our synthesized CsPbBr3 NRs.The LED device showed a strong green emission.All of these shows the ability of halide perovskite nanocrystals for applications on photoelectron,such as optical communication,display,lightning and so on.
