Influence of selenization temperature on synthesis, morphology, and properties of nanostructured CoSe2 films

03.01.2015 | Jen‐Bin Shi, Po‐Feng Wu, Chia‐Tze Kao, Ming‐Way Lee, Chih‐Chieh Chan, Ping‐Chang Yang, Cheng‐Li Lin, Rui‐Yo Huang, Y ..., Crystal Research and Technology, 2015

Nanostructured cobalt selenide (CoSe2) thin films were deposited on a glass substrate using the selenization of Co films at different selenization temperatures (300 °C, 400 °C, and 500 °C) in a pure Se vapor for two hours. The morphology and structure of the as‐deposited films shows that the ...

Materials, Vol. 8, Pages 149-161: Synthesis of Co3O4 Cotton-Like Nanostructures for Cholesterol Biosensor

31.12.2014 | Elhag, Sami ; Ibupoto, Zafar Hussain; Nour, Omer ; Willander, Magnus, Materials, 2014

The use of templates to assist and possess a control over the synthesis of nanomaterials has been an attractive option to achieve this goal. Here we have used sodium dodecyl sulfate (SDS) to act as a template for the low temperature synthesis of cobalt oxide (Co3O4) nanostructures. The use of SDS ...
