The authors have developed a new method to fabricate patterned W18O49 nanowire arrays by combination of thermal evaporation and lift-off technology. It is found that the phosphoric acid processing of the lift-off technology has strong effect on the field emission property of W18O49 nanowires.
Here we have successfully synthesized patterned W18O49 nanowire arrays in large scale by lift-off way, which has described in our report also to this conference. In order to remove the aluminum oxide layer, the sample was put into the phosphoric acid with a concentration of 60 % (volume ratio). The treatment time in 90°C water bath was usually about 4 hours. The treated and untreated tungsten oxide...
