Organic-inorganic perovskite compounds can be fabricated by various combination of organic amines and lead halides. To investigate the effect of amines with different classifications, we introduced primary, secondary, and tertiary-alkyl amines to perovskite compounds. X-ray diffraction measurements showed that the network of lead halide octahedra was changed, depending on the classification of amines. Exction absorption peaks were observed for each compounds, and were shifted depending on the classification of amines. This suggested that the classification of amines affects the structures and optical properties of perovskite compounds.
