Study on Raman line at 1080.2cm−1 in ZnO thin films prepared under high RF power

Heterogeneous phase formation in diluted magnetic semiconducting Zn1−x−yCoxAlyO (CAZO) nanoparticles

“…4) indicate the multi-phonon processes occurring in ZnO. 37 The presence of CoO compounds is indicated by bands centered at around 176, 494, 529, 630, 702 and 721 cm À1 . The vibrational mode of CoO can occur in two phases of Co 3 O 4 and Co 2 O 4 with similar position of Raman modes.…”

Controlled morphologies and optical properties of ZnO films and their photocatalytic activities

“…7. Wurtzite ZnO belongs to the space group P6 3 mc, which has eight sets of phonon modes: 2E 2 , 2A 1 , 2E 1 and 2B 1 , according to the group theory [49][50][51]. Among them, the 2B 1 modes are neither Raman nor infrared active.…”
