Investigations of the power-dependent PL spectra in different configurations. (a) Power-dependent PL spectra of WSe2/Nanocavity. (b) WSe2/Au Film. (c) WSe2/Sapphire. The excitation laser has energy of 1.96 eV. (d–f) Integrated PL intensity of WSe2/Nanocavity with left peak from 1.65 to 1.73 eV and right peak integrated from 1.73 to 1.76 eV (d), WSe2/Au Film with peak integrated from 1.55 to 1.77 eV (e), and WSe2/Sapphire with peak integrated from 1.46 to 1.76 eV (f), as a function of laser power.
