Xy. Ma et al., PHOTOLUMINESCENCE OF A SILICON-OXIDE FILM FORMED BY ANODIZATION IN THE ELECTROPOLISHING REGION IN HF SOLUTION, Journal of physics. Condensed matter, 7(14), 1995, pp. 2901-2907
This paper reports the photoluminescence (PL) Of a silicon oxide film
formed by anodization in the electropolishing region in HF solution. T
he PL is preliminarily believed to be due to certain light-emitting ce
ntres in the silicon oxide film. In addition, the paper suggests that
not all the PL of anodized silicon formed in HF solution can be solely
ascribed to the porous silicon.
