Rapid growth of the CH 3 NH 3 PbCl 3 single crystal by microwave irradiation.

We report a rapid growth of the CH 3 NH 3 PbCl 3 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) mm 3 . 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 CH 3 NH 3 PbCl 3 single crystal with these outstanding properties could be potentially applied for any optoelectronic application with scale-up production.
