英文摘要	characteristic absorption bands of cr3+ peaked at 425 nm and 600 nm were observed in high optical quality cr2+ :zns prepared by the diffusion method, which were attributed to the cr3+ ion in an interstitial octahedral coordination site. the corresponding transition scheme was analyzed based on the ligand field theory. further research indicated a positive correlation between cr3+ concentration and cr doping level as well as oxygen partial pressure. dft calculations of formation energies for different defect combinations confirm the spontaneous emergence tendency of cr3+ during diffusion process with a preference for interstitial, s2--octahedrally coordinated site. at the same time the presence of o2- at an interstitial site could further lower the system energy as well as providing charge compensation, thus increasing the cr3+ concentration.
