We employ analytical and physical tools to explore photoelectrochemcial properties of nanomaterials at single–particle, single-molecule level.

Electrogenerated chemiluminescence of materials

Electrogenerated chemiluminescence (ECL), also known as electrochemiluminescence, is an analytical technique based on electrochemically generated reactive species to form an excited state. The formation, evolution, and devolution of such excited state(s) can be readily tracked using our newly developed Spooling ECL spectroscopy technique.

Nano(photo)electrocatalysis of single semiconductive crystals

Semiconductors are one of the fundamnetal basis in photoelectrons, where light converts to a energy. The performace of individual photoelectrode governs the overall performance of a device (i.e., photoelectrochemcial cell, photovoltaics) that can be estimated via single-partcile photocurrent measurements and scanning electrochemcial microscopy (Nano-SECM) along with single-molecule fluorescnce microscopy. The obtianed fundamental details enable us to predict kinetic and performance of semiconductor nanosystems an single-particle level.
