Abstract

A vapor deposition method for coating a substrate with a porous zeolitic film. The method includes two steps. The first step is to irradiate a zeolite with a pulsed laser beam to vaporize the zeolite in a plume adjacent to the zeolite. The second step is to intercept the plume on the substrate to form the porous zeolitic film. A piezoelectric substrate can be used to produce a chemical sensor.
