Use of amorphous monodispersed spinel film electrode in photo-electrochemical cells

A high purity amorphous spinel film (CdCr2S4) electrode composed of monodispersed grains has been successfully deposited on an ordinary glass and conducting glass (FTO) substrates from aqueous medium using a simple, inexpensive, reproducible chemical bath method at ambient temperature. The as-deposited film composed of small elongated particles of 100–150 nm in length and 10–20 nm in diameter aggregated into large monodispersed spherical clusters of 100–400 nm in diameter. Furthermore, the influence of this CdCr2S4 film electrode on photo-electrochemical properties was studied and reported.
