Starting materials: lead (II) acetate, CH3NH3+ (by adding a 40% solution of CH3NH2 in water), concentrated HCl

Product: Colorless MAPbCl3 crystals

Description: CH3NH3PbCI3 was synthesized from lead (II) acetate and CH3NH3+ dissolved in concentrated HCl solution. The aqueous solution was cooled from l00°C to room temperature to obtain the colorless crystals.

Method: Temperature-dependent Guinier-Simon photograph

Description: No method specified. Refer to Page 6374 Table I.
