Tungsten selenide (WSe2) film was successfully deposited on FTO substrate by brush plating technique. The film was uniform and well adherent to the substrate and annealed to 300 °C and 500 °C. As the annealing temperature was increased the orientation of the crystallites was more randomized than in the as-prepared film. The structural and optical properties of the film were investigated by XRD, SEM, EDAX, UV-Visible and PL. The XRD pattern indicates that this film was crystallized in the hexagonal structure.
Keywords: WSe thin film, morphology.

Coming from my observation, shopping for technology online may be easily expensive, but there are some guidelines that you can use to obtain the best deals. There are always ways to locate discount offers that could make one to have the best technology products at the cheapest prices. Great blog post.
Wow! This can be one particular of the most beneficial blogs We have ever arrive across on this subject. Actually Wonderful. I’m also an expert in this topic therefore I can understand your hard work.
