摘要
The enhanced visible absorbance related to electrochromic response (ECR) of CdS nanocrystals (NCs) thin film in aqueous solution was firstly investigated to elucidate the detailed electrochemiluminescence (ECL) mechanism of semiconductor NCs/H(2)O(2) system. The recovery efficiency of ECR was found as the key factor to affect the intensity of ECL This preliminary study between ECR and ECL of semiconductor NCs in aqueous solution can provide the profound guidance to fabricate enhanced "signal-off" kind ECL sensors to widen its application in analytical field.
