SnO2 films have been formed by the thermal vacuum deposition of Sn, pu
re Sn doped by Te and J(2) has been formed and also Sn doped by Cu wit
h post-treatment under controlled oxygen atmosphere has been formed. I
odium had been introduced into the initial mixture as a SnJ(2) to form
a better modified film surface for sensivity increase. The results of
influence of annealing in dynamic vacuum conditions on SnO2 Alms prop
erties are shown. (C) 1997 Elsevier Science S.A.
