Abstract
CdTe nanoparticles were synthesized in aqueous solution by colloidal method. The absorption and photoluminescence(PL) spectrum of the synthesized CdTe nanoparticles revealed the strong exitonic peak in the visible region. Photocurrent of CdTe nanoparticles were observed in the structure of Al/CdTe/ITO that was fabricated by spin coating of CdTe nanoparticles. The wavelength dependence of photocurrent was very similar to the absorption spectrum, indicating the charges generated by the absorption of photons give direct contribution to photocurrent. This study suggests that CdTe nanoparticles are very prospective materials for optoelectronics.
