Abstract

Abstract : High crystalline quality all-inorganic CsPbBr3 single crystals were obtained via a facile one-step solution growth method. The (002) X-ray rocking curve is as narrow as 0.043°. Abstract : In this report, a facile one-step solution growth method has been proposed to synthesize high-quality all-inorganic CsPbBr3 single crystals. High-resolution X-ray diffraction, photoluminescence (PL), and current–voltage techniques have been performed to study the properties of CsPbBr3 single crystals. The results have shown that the as-grown CsPbBr3 single crystals exhibited a narrow X-ray rocking curve with a FWHM (full width at half maximum) of 0.043°, a narrow room-temperature PL spectrum with the FWHM of 18.9 nm, and extremely low density of traps (∼5.1 × 10 9 cm −3 ). The results shown in this work will provide a valuable strategy for the fabrication of high-quality all-inorganic CsPbBr3 single crystals.
