SEM, PL and Raman characterisations on 6 month aged samples. a, b SEM micrographs of the 1L-MoS2 without coating and with PMMA coating after aging. Scale bars are 20 µm. c, d PL spectrum mapping using A exciton peak area of 2D spiral type MoS2, without and with PMMA coatings after aging, respectively. Scale bars, 5 µm. e, f Raman spectrum mapping using E12g peak area of 2D spiral type MoS2, without and with PMMA coatings after aging, respectively. Scale bars, 5 µm
