Effect of Er³⁺ doping on structural, morphological and photocatalytical properties of ZnO thin films

The effect of alpha particle irradiation on electrical properties and defects of ZnO thin films prepared by sol-gel spin coating

“…One high intensity peak located at 436 cm −1 corresponds to the E 2 (high) mode and confirmed the ZnO wurtzite structure. The E 2 (high) mode is associated with the motion of oxygen atoms [30]. The peaks located at 396 cm −1 and 408 cm −1 correspond to the A 1 (TO) and E 1 (TO), respectively.…”

“…The two E 2 branches (non-polar) are Raman active only. The E 2 (low) mode is related to the Zn sublattice, whereas the E 2 (high) mode is associated with the motion of oxygen atoms [30]. The B 1 (low) and B 1 (high) branches are inactive or silent modes [31].…”

“…The strong peaks observed correspond to E 2 (low) phonon mode at about 99 cm −1 and the E 2 (high) phonon mode at about 438 cm −1 indicative of the ZnO hexagonal wurtzite crystal structure. The E 2 (low) mode is related to the Zn sublattice, whereas the E 2 (high) mode is associated with the motion of oxygen atoms and sensitive to internal stress [30,134]. The broad peak located at 575 cm −1 corresponding to the A 1 (LO) phonon mode, is related to lattice defects such as oxygen vacancies and Zn interstitials [11].…”

Cerium-Oxide-Nanoparticle-Decorated Zinc Oxide with Enhanced Photocatalytic Degradation of Methyl Orange

“…In recent years, rare-earth (RE) metals have been used as dopants in RE/ZnO; these include Er [21,22], Eu [23][24][25], Nd [26,27], Tm [28], and La [29][30][31]. Suwanboon et al synthesized La-doped zinc oxide nanoparticles (La/ZnO NPs) using a precipitation and mechanical milling technique, and they investigated the blue-light-fluorescent-lamp-driven photodegradation activity of methyl blue.…”

FABRICATION AND I-V CHARACTERISTICS OF p-Si/n-ZnO:Er HETEROJUNCTIONS

“…[4][5][6][7][8][9]. Electrical, optical and structural properties can be modified with deposition parameters or dopant elements [10][11][12][13]. In recent years, zinc oxide (ZnO) films doped with Rare Earth (RE) elements have been taken attention due to their superior optical and electrical properties.…”
