抜粋

We perform HF treatment to a-Si:H nanoball films fabricated by the double-tubed coaxial-line-type microwave plasma chemical vapor deposition (MPCVD) system. By HF treatment, Photoluminescence wavelength shifted from 760 nm to 590 nm. We have determined the diameter of Si nanocrystals by X-ray diffraction (XRD) and transmission electron microscopy (TEM). It is found that the diameter of Si nanocrystals decreases from 5 nm to 3.7 nm, by HF treatment.
