Abstract

A method was developed to fabricate luminescent films at around room temperature based on successive ionic layer adsorption and reaction (SILAR). Nanocrystalline CePO₄:Tb³⁺ films were deposited on bare or surface-modified silica glass substrates through immersion in cation (Ce3+ and Tb³⁺) and anion (PO4 3) solutions successively. Experimental conditions for the successful deposition of the films were explored to obtain better luminescent properties related to redox sensibility. The intensity of photoluminescence from CePO₄:Tb³⁺ was increased linearly with increasing the number of SILAR cycles. Sensibility of the nanocrystalline CePO₄:Tb³⁺ films against the oxidation by KMnO4 and the reduction by L(+)-ascorbic acid in aqueous solutions was proved to be superior to that of a dense and flat CePO₄:Tb³⁺ film fabricated by a common solgel dip-coating method.
