Observation of anodic electrochemiluminescence from silicon quantum dots for the detection of hydrogen peroxide

Silicon quantum dots (QDs) with stable positively charged intermediates are prepared using chemical etching to generate strong anodic electrochemiluminescence (ECL) under a positive potential. Their surfaces could be passivated in the presence of strong oxidants, leading to enhanced ECL and offering...

Description
Summary:Silicon quantum dots (QDs) with stable positively charged intermediates are prepared using chemical etching to generate strong anodic electrochemiluminescence (ECL) under a positive potential. Their surfaces could be passivated in the presence of strong oxidants, leading to enhanced ECL and offering the ability to carry out analysis for hydrogen peroxide. Silicon QDs with stable positively charged intermediates are prepared using chemical etching to generate strong anodic electrochemiluminescence for the detection of hydrogen peroxide.
