This work describes a comparative study on zinc oxide/nickel oxide (ZnO/NiO) nanostructures deposited on glass substrates by chemical bath and modified bath. (CBD). and (M-CBD) techniques. The photoactivity of ZnO/NiO nanostructure films was tested on Rhodamine B (RB) dye under sunlight. https://journeysgiftes.shop/product-category/collections/
