Starting materials: Acetonitrile, HI, I(CH2)2NH2, PbI2

Product: Orange plate-like crystals

Description: In 6:2:1 molar ratio HI, I-(CH2)2-NH2, and PbI2 were added to an acetonitrile solution. It was stirred for a short time at room temperature, forming a clear and yellow solution. It was then held at room temperature and allowed to evaporate, leaving behind crystals of the perovskite after a few hours.

Method: UV-vis absorption

Description: A Lambda 19 Perkin-Elmer spectrometer using a Specac variable temperature cell P/N 21525 was used to directly measure the absorption spectra.
