摘要: Abstract The deposition of undoped, aluminum and/or holmium doped and co-doped zinc oxide thin films on different substrates was achieved using a very simple versatile aqueous solution method. effect the precursor concentration morphological structural characteristics, as well optical properties undoped ZnO also investigated. AFM investigations have revealed that morphology is smooth homogeneous. room-temperature photoluminescence (PL) absorption (UV–vis) as-obtained were investigated, well. A strong UV emission (380 nm) recorded for films. band gap value obtained ranging between 3.01 eV 3.56 eV, depending nature dopant.
