SINGLE LAYER NANOCOMPOSITE PHOTORESPONSE DEVICE

摘要

A photoresponse device comprising a nanocomposite photoactive material is provided. The photoactive layer comprises a nanocomposite material of metal oxide nanoparticles dispersed within a photosensitizing organic semiconductor formed on a substrate. Methods of characterizing the nanocomposites are provided and demonstrate commercially relevant electrical and photodetection properties, particularly the ability to operate as a photodiode, photoconductor or photocapacitor. An economical process for preparing the nanocomposite and the photoresponse device is also provided as well as applications.
