Molybdenum trioxide: a key component in resonance effects for an optical reflection system

In this study, the coherent scattering model (CSM) and the iterated ray method (IRM) were applied to simulate the reflectance of a six-layer system composed of a BK7 prism, molybdenum trioxide film (MoO3), gold nanoparticles (Au-NPs), water, a BK7 substrate, and air. Reflectance spectra were generated and compared for the two main phases of MoO3, ¿ and ß. The theoretical reflectance response was analyzed by systematically varying the wavelength of the incident light, the thickness of the MoO3 film, and the surface coverage percentage of Au-NPs on the MoO3 film for each phase. A pronounced plasmonic resonance effect was observed for the ß phase of MoO3 under specific monolayer thickness conditions. © 2025 IOP Publishing Ltd.
