College of Science _ University of Kerbala has discussed the M.A thesis which is entitled” Effect of Doping by Copper Oxide Properties of Zinc Oxide Nanoparticles”.

Being submitted by Wajdan Amer Abdul Zaid, the study aims at preparing thin films using sol-gel technique and examining their structural, optical, and electrical properties in formation of gas sensors.
The thesis evaluates performance of films used in manufacture of sensors, such as hydrogen sulfide and nitrogen dioxide gas sensors.
The results show that copper oxide doping contribute to reducing energy gap and enhance sensitivity of films. The 0.75% doped sample achieved highest response to both gases at an optimal operating temperature of 150°C, with a sensitivity of 241.81% for hydrogen sulfide and 194% for nitrogen dioxide.
The thesis confirms possibility of employing these results in developing highly efficient nanoscale gas sensors.
