Starting materials: BABr (synthesized), PbBr2, HBr

Product: Colorless single crystals

Description: (BA)2PbBr4 crystals were synthesized by mixing BABr, and PbBr2 into a saturated HBr solution at a molar ratio of 2:1. Complete dissolution was achieved by heating to boiling with constant stirring for ~30 minutes. Upon slowly cooling, at a rate of 1°C/min to room temperature, the crystals precipitated. The crystals were removed by suction filtration and were dried in a vacuum.

Method: Photoluminescence microscopy

Description: PL spectra were recorded in a PL microscope. A Janish Research Company ST-500 microscope cryostat using a Coherent OBIS 375LX laser was used for the measurements.
