摘要
Photoluminescence (PL) of anodized porous silicon was investigated using several kinds of alcohols and deionized water as the solvent of an anodic solution. Correlation factors between PL characteristics and some physical parameters of the solvent were analyzed, which indicated that surface tension had definitive effects on PL characteristics. The peak energy and full width at half maximum of PL increased with the decrease in surface tension. Results are explained by a passivation effect of the hydrogen bubbles generated by the anodic reaction.
