Abstract
All-inorganic halide perovskites CsPbX3 (X = Cl, Br, I) have shown encouraging potential for optoelectronic devices. In this work, the synthesis of CsPbCl3 perovskites is reported by a simple approach using three different solvents namely dimethylformamide (DMF), dimethyl sulfoxide (DMSO) and a mixture of dimethyl sulfoxide and dimethylformamide. The structural, optical and electrical properties of CsPbCl3 perovskites are compared to identify the optimal solvent for the synthesis process. The DMSO-based CsPbCl3 perovskite exhibits an optical bandgap value of 2.96 eV along with high photoluminescence intensity, high charge carrier mobility (29.8 cm2/V-s), and low resistivity (8.06 x 107 Ω-cm) compared to the other two CsPbCl3 perovskites. These results indicate that DMSO solvent plays an important role in achieving desired optical and electrical properties of CsPbCl3 perovskites suitable for optoelectronic devices.
期刊介绍：
Optical Materials has an open access mirror journal Optical Materials: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
The purpose of Optical Materials is to provide a means of communication and technology transfer between researchers who are interested in materials for potential device applications. The journal publishes original papers and review articles on the design, synthesis, characterisation and applications of optical materials.
OPTICAL MATERIALS focuses on:
• Optical Properties of Material Systems;
• The Materials Aspects of Optical Phenomena;
• The Materials Aspects of Devices and Applications.
Authors can submit separate research elements describing their data to Data in Brief and methods to Methods X.
