High quality monolayer MoS? solution
The first monolayer MoS? solution that is made out of synthetic 99.995% quality MoS? crystals for superior quality and reliability. Result of a month long processing steps.
Consistent and reliable PL & Raman results.
Enhanced PL signal compared to solution prepared out of MoS2 nano-powders.
Environmentally stable
In suspension of your choice (ethanol, methanol, benzene etc.)
MoS2 solution has been prepared from high purity synthetic MoS? single crystals. The end product is optically active and environmentally stable. The PL spectrum displays peak at 1.89 eV and 2.05 eV corresponding to the band edge and spin-orbit emission. The Raman spectrum displays 19cm-1 difference between in plane and out of plane (E2g and A1g) modes. The FWHM of the Raman peaks are only 0.5cm-1 larger than the exfoliated MoS2 monolayers.
Characterization
Raman spectroscopy: Raman spectroscopy data is taken over a large area. Displays peak at 386cm-1 (E2g- in plane-) and 405cm-1 (A1g out-of-plane) and the FWHM (full-width-at-half-maximum) is less than 5-6cm-1. Photoluminescence (PL): PL peak at 1.89 and 2.05 eV. Please note that the solution might contain monolayer and few-layer flakes.
