摘要: By maintaining α-Ag(DM)2 (DM = C10H8N4) around room temperature (RT) () during ultraviolet–visible (UV–vis) irradiation, a series of photochemical products named β was obtained. The solid comprised structurally different compounds. All the phases share original chemical formula Ag(DM)2 and exhibit semiconducting behaviour, yet they differ from each other in their XRD patterns. They are divided into two phases: β1 β2. Compared with pattern α phase, β1 phase exhibited peaks at same 2θ-angles but relative intensities, while β2 phase totally patterns those or phases. actual composition particular 'β' is dependent upon irradiation time, can be controlled continuously. Around RT, exhibits metallic conductivity, suggested to semiconductors. As result, one continuously finely control electrical resistivity by UV modify it mixture α, and/or
