The films were fired at different temperatures in the 800-1000°C range. The content of ?$\\alpha$?-terpineol, a component of the organic vehicle, was varied in the range 0.0046-4 wt%. The ?$NO_2$? sensing properties of the films were investigated as a function of the materials characteristics. The content of ?$\\alpha$?-terpineol strongly influenced the eleactrical conductivity and its activation energy. The smaller the amount of ?$\\alpha$?-terpineol, the lower the ?$NO_2$? response of the films and the larager their conductivity. Such increase in conductivity is attributed to a different oxygen surface layer on the ?$SmFeO_3$? surface, which is induced by the decomposition reaction of ?$\\alpha$?-terpineol during sintering. The activation energy is correlated with the ?$NO_2$? sensitivity and the materials characteristics (influenced by the preparation parameters).

Večanje prevodnosti se pripisuje različnemu sloju kisika na površini ?$SmFeO_3$?, ki ga inducira reakcija razpada terpineola med sintranjem. Aktivacijska energija je korelirana z občutljivostjo ?$NO_2$? in karakteristikami materiala (te so odvisne od parametrov priprave).
