Investigation of the photocatalytic and optical properties of the SrMoO/g-CN heterostructure obtained via sonochemical synthesis with temperature control.

In this work, nanomaterials of the SrMoO/g-CN heterostructure were synthesized in a single step by the sonochemical method with controlled temperatures. Structural and morphological investigations indicate the formation of heterojunctions, revealing the presence of g-CN (CN) in the heterostructures and an interface region between the phases. Optical analyzes show broadening of the wavelength absorption range and a decrease in the photoluminescence (PL) intensity of the heterojunctions compared to the CN emission spectrum, proving a decrease in the recombination of the photogenerated charges.

Integration of experiment and computational modeling on the Tb doping process in CaMoO4 obtained by USP method: An efficient way to obtain photoluminescent materials.

In this paper, we present a combined experimental and theoretical study to disclose, the structure, electronic and optical properties of CaMoO 4 :xTb 3+ ( x = 1%, 2%, and 4%) microspheres. The microspheres were prepared by ultrasonic spray pyrolysis method and characterized by experimental and theoretical techniques. Theoretical calculations and XRD patterns indicate that these crystals have a scheelite-type tetragonal structure.
