    Modified electrodes with diluted magnetic semiconductor nanoparticles (Q-Cd1-XMnXS) were fabricated by immobilizing them on a self-assembled monolayer of hexanedithiol prepared on the Au electrode. Photoirradiation of the Q-Cd1-XMnXS-modified electrode in the presence of triethanolamine afforded stable anodic photocurrents. In the presence of external magnetic fields, larger reduction (∼8%) of photocurrent from the Q-Cd1-XMnXS-modified electrode was observed as compared with that from a cadmium sulfide nanoparticles (Q-CdS). This magnetic field effect is most likely ascribed to the quantum size effect (quantum confinement effect) and exchange effects in the exciton states due to Mn2+ ions in Q-Cd1-XMnXS.
