Starting materials: Solid CsBr, BiBr, 9-M HBr, Solid AgBr
Product: red-orange crystals
Description: First, solid CsBr (0.426 g, 2.00 mmol) and BiBr (0.449 g, 1.00 mmol) were dissolved in 10 mL of 9-M HBr. Afterward, solid AgBr (0.188 g, 1.00 mmol) was added to the mixture. The vial was then capped, heated to 110º C for 2 hours, and cooled to room temperature by controlling the cooling rate to 2ºC/hr or 1ºC/hr. The obtained crystals were filtered on a glass frit and dried under low pressure overnight.
Method: X-ray diffraction
Description: A crystal was coated in Paratone-N oil, placed on a Kapton loop, and transferred to a Bruker D8 Venture diffractometer with a Photon 100 CMOS detector. Data was collected using ωv and ψ scans with 18-keV synchrotron radiation (λ = 0.68880 Å)

Product: orange powder
Description: First, solid CsBr (0.426 g, 2.00 mmol) and BiBr (0.449 g, 1.00 mmol) were dissolved in 10 mL of 9-M HBr. Afterwards, solid AgBr (0.188 g, 1.00 mmol) was added to the mixture. The vial was then capped, heated to 110º C for 2 hours, and cooled to room temperature. As a result, an orange-powder precipitate formed and was filtered on a glass frit and dried under low pressure overnight.
Method: Estimation through Tauc plot.
Description: Cary 6000i UV-Vis spectrometer equipped with an integrating sphere was used in absorbance mode to collect absorption data. The powder was pressed and mounted on a quartz slide such that incident light was normal to the surface.

Method: Photoluminescence
Description: Room-temperature steady-state emission spectra were collected on powders mounted on quartz slides using a Horiba Jobin-Yvon Spex Fluorolog-3 fluorimeter equipped with a 450-W xenon lamp and a thermoelectrically-cooled R928P detector.
