Room temperature multi-phonon upconversion photoluminescence in monolayer semiconductor WS2

Two-dimensional materials show promise for photon upconversion processes due to their strong photon-exciton and phonon-exciton interactions. Here, the authors report room temperature upconversion photoluminescence in monolayer WS2 with high energy gain up to 150 meV based on variable temperature.
