Appeal No. 1996-3659
Application No. 08/237,484
1. A vapor deposition method for coating a substrate with
a porous zeolitic film, the method comprising the steps of:
(a) irradiating a porous zeolite with a pulsed laser
beam of at least sufficient duration and intensity to
vaporize the zeolite in a three-dimensional plume
adjacent to the zeolite; and
(b) intercepting the plume on the substrate to form
the porous zeolitic film.
10. A sensor, comprising:
(a) a piezoelectric substrate; and
(b) a porous zeolitic film coated on the
piezoelectric substrate, the porous zeolitic film formed
by irradiating a porous zeolite with a pulsed laser beam of
at least sufficient duration and intensity to
vaporize the zeolite in a three-dimensional plume
adjacent to the zeolite and then intercepting the plume
on the substrate to form the porous zeolitic film.
