ZnO nanorods have been grown on indium tin oxide (ITO) coated flexible polyethylene terephthalate (PET) substrates by a hydrothermal method. Hybrid photosensing devices have been fabricated with S and N co-doped graphene quantum dot (SN-GQD) sensitized ZnO nanorods and a conducting polymer poly (3-hexylthiophene) (P3HT). The photoresponse behaviors have been investigated for hybrid devices with and...
Photoelectrochemical properties of ZnO nanorods have been widely investigated due to low cost, easy synthesis process and high carrier mobility. However, weak photoabsorption in visible region is the major bottleneck of ZnO for solar cell applications. To improve the photoelectrochemical behavior, it is necessary to sensitize ZnO nanorods with semiconductor quantum dots or nanoparticles. To enhance...
Structural and optical properties of ZnO nanoparticles of diameter ∼ 5 nm, which are synthesized in a sol-gel route, have been studied using a variety of experimental techniques. The photoluminescence (PL) study that has been carried out on these particles in the atmospheric and vacuum conditions shows a suppression of the defect related green luminescence (GL) band and a simultaneous enhancement...
We report the absorption and photoluminescence (PL) properties of dilute InPN layers grown by liquid phase epitaxy. All samples were characterized by high resolution X-ray diffraction at room temperature. The band anticrossing model accounts very well for recent experimental results obtained on different samples. Our results indicate that a maximum amount of 0.2% nitrogen has been incorporated in...
