Abstract: 

Nanocrystalline Calcium oxide (CaO) thin films were synthesized on glass substrate by using chemical bath deposition (CBD) method. The variation in structure, morphology, and optical properties of CaO thin films annealed at various temperatures were analyzed in detail. The film showed a high transmittance (60%) and a wide band gap ranges from 3.62 to 3.39 eV.
