Abstract

The aim of this work was twofold. Firstly the incorporation of thermochromic bis(diamine)copper(II) chloride complexes and the derived diammoniumtetrachlorocuprate(II) salts, into silica sol-gel materials was investigated examining the differences in thermochromic behaviour including mechanisms of interaction between the free compounds and the doped materials. Secondly the aqueous sol-gel chemistry of zinc acetate was studied examining the nature of condensed phases from low (0.1M) and high (saturated, 1.38M) concentration solutions. The effect of low levels of sulphate ions on the condensation products produced from saturated solutions was also investigated. Finally zinc oxide thin films were prepared from dispersions of zinc hydroxyacetate materials for acoustic wave devices.

An initial study into the use of dispersions of zinc hydroxyacetate materials for zinc oxide thin film and acoustic wave device preparation showed that aqueous sol-gel routes to zinc oxide thin films are feasible although the coatings prepared on silica substrates were capable of supporting bulk acoustic waves and not surface acoustic waves.
