NettetDoping of TiO 2 with suitable ions [21] such as chromium, iron, or tin or with nonmetallic atoms like sulfur [22], nitrogen [23], or carbon [24] induces interband states. Hence, additional absorptions of lower energy (i.e., longer wavelengths) lead to the promotion of electrons into the conduction band of TiO 2 [19,25]. Nettet1. des. 2008 · For the smallest CdSe Q-dots, the difference between the quasi-particle gap and the optical band gap gives the electron-hole Coulombic interaction energy (J(e1,h1)).
