We study the effect of one-dimensional (1D) photonic crystal heterojunction (h-PhC) on the light absorption and light emission of monolayer molybdenum disulfide (MoS2), and obtained the analytical solution of the light absorption and emission of two-dimensional materials in 1D h-PhC. Simultaneously enhancing the light absorption and emission of the medium in multiple frequency ranges is easy as h-PhC has more models of photon localization than the common photonic crystal. Result shows that h-PhC can simultaneously enhance the light absorption and emission of MoS2 and enhance the photoluminescence spectrum of MoS2 by 2-3 orders of magnitude.
