a Molecular structure of DDT. b–e Optical microscope images of DDT crystal grown on MoS2 under 405-nm laser irradiation (scale bar = 5 μm). DDT crystal overlaid on MoS2 (DDT/MoS2) shows green emission while DDT crystal overhang outside of MoS2 emits blue fluorescence. f PL spectra of DDT overhang and DDT/MoS2. g PL spectra and photos of DDT aqueous suspension and DDT/MoS2 aqueous suspension. h PL spectra of 1 mM DDT DMF solution. i PL spectra of DDT/MoS2 aqueous suspension prepared by precipitating 1 mM DDT DMF solution into MoS2 aqueous suspension. TRPL spectra of 1 mM DDT solution in DMF and DDT/MoS2 aqueous suspensions at (j) RT and (k) 77 K.
