Abstract
A method for fabricating metal-coated organic crystal wherein a reaction of an organic crystal with transition metal salt in alkaline aqueous solution under visible light irradiation, wherein, when energy at the top of valence band of the organic crystal is defined as A (eV) and energy at the bottom of conduction band of the organic crystal is defined as B (eV), redox potential C (V) of transition metal ion or transition metal complex ion, when said transition metal salt is dissolved in the alkaline aqueous solution, these three parameters should satisfy the following relation (1): −A−4.5≧C≧−B−4.5.
