Structure characterisation of the orientated (CH3NH3)3Bi2I9 coating on quartz. a X-ray diffraction results from the coating and powdered samples. b Optical microscope and c scanning electron micrograph of the (CH3NH3)3Bi2I9 coating processed by depositing and drying of the solution of BiI3 and CH3NH3I in N,N-Dimethylmethanamide. The scale bars represent 25 μm
