Starting materials: PbI2, toluene, butyric acid, butylamine, formamidinium acetate
Product: Powder film on glass substrate
Description: PbI2, toluene, butyric acid, and butylamine were mixed in a capped flask. Separately, formamidinium acetate was dissolved in toluene and butyric acid. The solutions are combined and stirred until a red solid precipitated. The solid was removed by centrifuging at 6000 rpm for 3 minutes. It was then re-dispersed in hexane and centrifuged again to obtain the final paintlike paste. The paintlike paste was then deposited on a glass substrate. A Pasteur pipette was used to spread the paste over the surface and was then allowed to dry.
Method: Photoluminescence Spectra
Description: A Horiba-Jobin Yvon Fluorolog-3 instrument was used on the films to measure photoluminescence spectra. Excitation was perpendicular to the film and emission was collected at an angle of ~15 degrees. The data was corrected according to the lamp and detector details by using algorithms from the equipment software.

Method: Diffuse Reflectance Spectra
Description: Diffuse reflectance spectra were measured in a Shimadzu UV 2450 instrument. A Ba2SO4 powder palette was the reference used.
