| 英文摘要 | we have investigated creation of variable concentrations of defects on tio2(110)-(1 x 1) surface by 266 nm laser using temperature programmed desorption technique. oxygen-vacancy defects can be easily induced by ultraviolet light, the defects concentration has a linear dependence on power density higher than 50 mw/cm(2) for 90 s irradiation. no observation of o-2 molecule and ti atom desorption suggests that uv induced defects creation on tio2(110)-(1 x 1) is an effective and gentle method. with pre-dosage of thin films of water, the rate of defects creation on tio2(110)-(1 x 1) is slower at least by two orders of magnitude than bare tio2(110)-(1 x 1) surface. further investigations show that water can be more easily desorbed by uv light, and thus desorption of bridging oxygen is depressed. |
