Patent number: 8673672Abstract: In the present invention, copper(I) selenide (Cu2-xSe) nanoparticles are fabricated by pyrolysis in an inert atmosphere. Uniformly dispersed Cu2-xSe particles are synthesized by altering Cu/Se ratio, the concentration of Se Precursors (TOP Se), reaction time and temperature. Analysis by inductively coupled plasma atomic emission spectroscopy (ICP-AES) of said Cu2-xSe nanoparticles reveals that the composition of the nanoparticles is Cu 1.95Se, wherein x=0.05. In addition, Cu2-xSe is dissolved in ethanol to deposit thin films by electrophoretical deposition (EPD) in an inert atmosphere, wherein a positive electrode and a negative electrode are employed. The positive electrode is made of stainless steel plate and the negative electrode is made of indium tin oxide on a glass substrate. Investigations on properties and surface morphology thereof in different electrophoretical conditions are carried out. The rate of EPD is found to significantly influence the quality of thin films.Type: GrantFiled: July 12, 2012Date of Patent: March 18, 2014Assignee: National Chung Cheng UniversityInventors: Chu-Chi Ting, Wen-Yuan Lee
