铕离子注入氧化硅膜光发射的研究
Photoluminescence From Eu Implanted SiO\-2 Thin Films
【摘要】 采用铕离子注入热生长SiO2 薄膜的方法,获得掺杂剂量为1014cm - 2及1015cm - 2的SiO2∶Eu3+ 硅基复合膜,研究了该薄膜的光致发光退火特性.经1000℃退火后观察到Eu3+ 的红光发射.在1200℃下氮气中退火观察到Eu2+ 450nm 的强光发射.讨论了Eu3+ 向Eu2+ 的转变
【Abstract】 The Eu doped SiO\-2 thin films are prepared by Eu ion implantation.The implanted doses of Eu ions are 10 14 cm -2 and 10 15 cm -2 ,respectively.No photoluminescence is observed for as\|implanted thin films.After annealing at 1000℃ in N\-2,the red light emission from doped SiO\-2 film,corresponding to the 5D\-0→ 7F J transition of Eu 3+ ,is observed.As the annealing temperature rises to 1200℃,a strong light emission band at wavelength of 450nm appears.The transition from Eu 3+ to Eu 2+ has been discussed.
