Abstract
This paper discusses how acidic solutions affect the variation of the refractive
index and thickness of a nanosize film of oxide composition (20 mol%
Bi<sub>2</sub>O<sub>3</sub>, 25 mol% Fe<sub>2</sub>O<sub>3</sub>, 55 mol%
TiO<sub>2</sub>), deposited on a glass substrate by the sol–gel method. When the film
is allowed to stand in the solutions, it simultaneously swells, with an increase of its
thickness, and dissolves. The swelling initiates an increase of the refractive index,
and the dissolution reduces it.
