Description

This product contains ReSe2 flakes solution in ethanol media. Other solutions are also available please drop a note during the checkout process about your desired solution. The ReSe2 solution has been developed by pulsed ultrasonic treatment of high quality ReSe2 crystals synthesized through flux zone technique to achieve high quality ReSe2 sheets dispersed in solution. The crystallinity of ReSe2 flakes has been confirmed through electron energy dispersive spectroscopy (EDAX), Raman spectroscopy (FWHM<5 cm-1), and scanning electron microscopy (SEM) measurements. Lateral sizes of ReS2 flakes deposited onto different substrates range from ~25nm to ~10 micrometers while thickness range from 1L to few and multilayers.

Note on volume, concentration, and solvent type: International shipping mostly allows only small volume shipping, thus we ship supersaturated 2D solutions (~100-300 mg/L depending on the type of 2D layers). These supersaturated solutions are designed specifically so that you can dilute to produce large volume (250-500mL) solutions. In our product, ethanol is used (and recommended) as the dispersant solvent owing to its environmental stability, thermal stability, dispersant properties, and non-contaminating nature. However, if your research needs other solvents, either contact us or drop a note during the check out process regarding your desired solution type.
