Using erbium acetate as an Er source, transparent ZnO films doped with Er were fabricated by sol-gel method through spin-coating on quartz substrates. The as-prepared ZnO:Er films were annealed in air at 400 • C for 6 h, at 600 • C, 800 • C and 1000 • C for 2 h, respectively. The ZnO:Er films exhibi
## Abstract Zinc oxide thin films have been prepared via a sol–gel process. The influence of annealing temperature on the structural and optical properties of the ZnO thin films has been investigated. The prepared ZnO thin films had a polycrystalline hexagonal wurtzite structure with no preferred o
