چکیده

Abstract Gadolinium oxide nanorod (Gd 2 O 3 NR) was fabricated on an n-type silicon substrate by catalyst-free glancing angle deposition (GLAD) technique. The as-grown sample annealed at 500 °C to investigate the impact of annealing structure and optical properties. XRD analysis reveals improvement in crystal after annealing. Field emission scanning electron microscope (FE-SEM) energy dispersive X-ray (EDX) confirm successful growth vertically aligned Gd NR with presence Gd, O, Si. Transmission (TEM) showed crystalline nature grown NR. Finally, UV–vis spectroscopy performed study A significant enhancement photon absorption (200–300 nm) observed, which can be attributed increased grain size, improved crystallinity, large generation electron–hole pairs. In addition, Tauc plot a decrease bandgap from 5.05 eV 4.98 °C.

Investigating structural, optical and photocatalytic properties of hydrothermally synthesized ZnO nanorod arrays with various aspect ratios

ZnO nanorods with various aspect ratios (by changing the time of growth between 0-240 min) were synthesized using hydrothermal method and were investigated using XRD, SEM, UV–Vis and PL. It was found that growth time is directly coupled with the length, orientation and aspect ratio of the nanorod arrays. The optical transmittance of the NR arrays indicated a regular decrement of average transmi...

Effect of Annealing Temperature on Structural, Electrical and Optical Properties of TiO2 Nanopowder

TiO2 nanopowder is prepared by simple sol-gel method using starting material as titanium isopropoxide with methanol and annealed at 600°C, 700°C and 800°C for 1 hour in air. X-ray diffraction pattern revealed the presence of both anatase and rutile phase in TiO2 specimens annealed at different temperatures. It is observed that the content of rutile phase and crystallite size increases with incr...
