Rapid growth of the CH3NH3PbCl3 single crystal by microwave irradiation

Abstract

We report a rapid growth of the CH₃NH₃PbCl₃ single crystal through microwave irradiation. A systematic evaluation of the structural and optical properties of the obtained single crystal was also conducted. 1 minute is the optimum microwave irradiation time that generated a large single crystal of dimension (5 × 5 × 2.5) mm³. The obtained crystal exhibits broad absorption in UV range and near-visible light luminescence under UV excitation with an optical bandgap around 2.8 eV. A fast and simple synthesis method of CH₃NH₃PbCl₃ single crystal with these outstanding properties could be potentially applied for any optoelectronic application with scale-up production.
