Photoluminescence (PL) from Er-implanted hydrogenated amorphous silicon suboxide ( a - SiO X : H 〈 Er 〉( x <2.0)) films was measured. Two luminescence bands with maxima at λ ≅ 750 nm and λ ≅ 1.54μ m, ascribed to the a - SiO x : H intrinsic emission and Er 3+ emission, were observed. Peak intensities of the two bands follow the same trend as a function of annealing temperature from 300 to 1000°C. Micro-Raman results indicate that the a - SiO x : H < Er > films are a mixture of two phases, an amorphous SiO x matrix and amorphous silicon (a-Si) domains embedded there in. FTIR spectra confirm that hydrogen effusion from a - SiO x : H < Er > films occurs during annealing. Hydrogen effusion leads to a reconstruction of the microstructure of a-Si domains, thus having a strong influence on Er 3+ emission. Our study emphasizes the role of a-Si domains on Er 3+ emission in a - SiO x : H < Er > films.

ABSTRACT1·54 jim light-emitting erbium-doped hydrogenated amorphous silicon films have been fabricated by standard low temperature (200 – 250 °C) PE CVD technique. The films were doped with erbium during the deposition by making use of a new fluorine-containing metalorganic compound Er(HFA)3*DME [where HFA=CF3C(O)CHC(O)CF3, DME=CH3OCH2CH2OCH3]. Photoluminescence spectra of the a-Si(Er):H films were studied within the range 0·6–1·7 pm at both 77 K and 295 K. A photoconductivity was also detected. The photo- to dark conductivity ratio was on the order of 103.
