Impact of YO Nanosheets on the Microstructural Characteristics of Alq Prepared via the Co-precipitation Route for Enhancement of Photodiode Performance.

In the present study, tris-(8-hydroxyquinoline) aluminum (Alq) and tris-(8-hydroxyquinoline) aluminum/yttrium oxide Alq/YO were synthesized by a facile chemical route. The crystal structure, surface morphological nature, and particle size were identified by X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) micrographs. Ag/Alq/p-Si/Al and Ag/Alq:YO/p-Si/Al diodes were fabricated by the thermal evaporation technique and the electrical characteristics were evaluated from the - plots in dark and under illumination intensity.
