Abstract:

Lutetium oxyorthosilicate (Lu2SiO5, LSO) films co-doped with Ce3+ and Pr3+ was synthesized on cleaned silicon (111) substrates by Sol-Gel route with a spin-coating technique. XRD patterns indicated that the films were crystallized into A-type Lu2SiO5 phase at 1000℃, followed by a phase transition to B-type Lu2SiO5 at 1100℃. SEM observations revealed that the surface of the films was smooth, homogeneous and crack-free when the samples were calcined under 1100℃. The average grain size of the crystal particles was 200-300 nm and the thickness of the thin film was about 320 nm when the coating layer number up to 10. The energy transference from Pr3+ to Ce3+ in Lu2SiO5 host was observed and discussed. The luminescence intensity of Ce3+ can be improved after Pr3+ co-doping.
