High quality monolayer WS? solution
The first monolayer WS? solution that is made out of synthetic 99.995% quality WS? 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 WS? nano-powders.
Environmentally stable
In suspension of your choice (ethanol, methanol, benzene etc.)
WS? solution has been prepared from high purity synthetic WS? single crystals. The end product is optically active and environmentally stable. The PL spectrum displays peak at 2.04 eV and 2.2 eV corresponding to the band edge and spin-orbit emission. The Raman spectrum display sharp peaks with FWHM around 5-6 cm-1
