Preparation and the Photoluminescence Properties of Er³⁺-Doped MoS₂ Thin Films

Abstract:

Molybdenum disulfide (MoS₂) thin films, layered quasi-two dimensional (2D) materials, have excellent optical and electronic properties for its special structure. In this paper, the surface morphologies, crystals structures and optical characteristics of MoS₂ and Er³⁺-doped MoS₂ (Er: MoS₂) thin film samples fabricated on the quartz substrates by sol-gel method were investigated. The result indicated that annealing made the crystallinity and optical absorption characteristics of MoS₂ thin films better. The light absorption and photoluminescence intensity was enhanced by doping Er³⁺. Moreover, the photoluminescence intensity increased with increasing doping concentration, but appears saturation tendency.
