Abstract

Magnesium selenide (MgSe) thin films were synthesized on glass substrates by spray pyrolysis technique at different substrate temperatures. Effect of substrate temperature on the physical properties of the films was investigated. XRD studies revealed that all the films exhibit cubic structure with a preferential orientation along the (2 0 0) plane irrespective of the substrate temperature. The band gap value decreases from 2.87 eV to 2.72 eV with increase in substrate temperature. The type of functional groups present in the samples is verified using FTIR spectrum.
