Abstract

Abstract: A series of emulsion microcrystals with different iodide content was prepared with double-jet method.Their light absorbtion was measured by U.V.spectrometry.Their ionic conductivity and photoelectron conductivity were determined with dielectric loss and microwave photoconductivity methods respectively.It was shown that the light absorbtion ionic conductivity and photoelectron conductivity enhance with the iodide content increase.The photoelectron decay obeys a second order reaction kinetic process.The iodide incorporation into the microcry.stals and the truncated technology made it possible to multiply the sensitivity of the cubic emulsion microcrystals.

Key words: emulsion, ionic conductivity, photoconductivity, truncated cubic
