Abstract
Measurements of the photoelectrochemical properties of nanocrystalline ZnS electrodes doped
with Mn^(2+) are presented and discussed. The observation of both anodic and cathodic photocurrent
is direct evidence for the nanocrystalline nature of the system. In-situ photoluminescence measurements
showed stable Mn^(2+) related photoluminescence over a large potential range. Due to the
unfavourable kinetics of electron
