Doping ZnO Hydrothermally Deposited Nanocrystals with Transitional Metals
PROCEEDINGS OF THE 2018 IEEE 8TH INTERNATIONAL CONFERENCE NANOMATERIALS: APPLICATION & PROPERTIES (NAP-2018)（2018）
Abstract
The ZnO doped with transitional metals - Ni or Co - were synthesized by chemical hydrothermal deposition. According to SEM study ZnO films obtained on Si wafers consist of separated nanocrystals with diameter up to 1 μm, 30 nm ALD ZnO sublayer changed the structure of hydrothermally grown ZnO films to array of densely packed pillars. It was shown that doping ZnO with Ni and Co decreased the exciton photoluminescence band compared to undoped ZnO crystals.
