Paper Abstract

AgI nanoparticles with zincblende structure are promising materials for laser based optical communication systems and therefore deserve to be optimally synthesized. We have explored ambient iodization as a strategy for controlled AgI nanoparticle growth on (a) mesoporous Ag foils, (b) Ag-Cu quasi-amorphous thin films and (c) Ag-Sb crystalline alloy films. The modified Ag surfaces obtained by chemical etching, Cu and Sb substitution seem to display an amazingly varied degree of interfacial control over the growth of AgI nanoparticles as investigated by XRD, SEM, optical transmission and photoluminescence. The nature of interfacial control and the associated modification of thin film growth mode are discussed on the basis of the present experimental results and currently available theoretical models.
