Abstract


The resonant nuclear reaction (RNR) technique has been used for determining the fluorine content in CdO thin films prepared by spray pyrolysis. The gamma rays observed were from the nuclear reaction $^{19}$F(p,$\alpha \gamma )^{16}$O, which presents a resonance at 340 keV bombarding energy. From the excitation curves the dependence of the fluorine content in the films on the wt % of NH$_{4}$F in the starting solution was observed. In order to understand the doping process, the RNR study was complemented with the other techniques of chemical and electrical analysis such as energy dispersive spectroscopy and the Hall effect.
