This product contains MoSe₂ flakes solution in ethanol. The MoSe₂ solution has been developed by ultrasonic treatment of bulk MoSe₂ high quality crystals synthesized through vapor transport (CVT) technique. Since the starting material (CVT grown MoSe₂ crystals) is highly crystalline, ultrasonic treatment to delaminate MoSe₂ layers yields highly crystalline MoSe₂ mono-, few-, and some thick layers suspended in ethanol solution. The crystallinity of MoSe₂ nanomaterials has been confirmed through electron energy dispersive spectroscopy (EDAX), Raman spectroscopy (FWHM<5cm-1), and scanning electron microscopy (SEM) measurements. Depending on the thickness of the layers, flakes deposited on different substrates produce light emission (photoluminescence). Lateral sizes of MoSe₂ flakes deposited onto different substrates range from ~10nm - ~10 um while thickness range from 1L to 10s of layers.
