Abstract

The light absorption and transmission of monolayer MoS₂ in a flexible one-dimensional defective photonic crystal (d-1DPC) are theoretically investigated. The study shows that the strong interference effect decreases the photon density in particular areas of the microcavity. The d-1DPC can reduce light absorption of the monolayer MoS₂ and enhance light transmission. The impact of monolayer MoS₂ light absorption on the localization effect of the photon is investigated when the monolayer MoS₂ and the organic light-emitting diode are located in the same microcavity. However, monolayer MoS₂ does not reduce the emission intensity from the microcavity by regulating the position of monolayer MoS₂ in the microcavity.
