| Description | Chemical exfoliation is one of the the most suitable routes towards large-scale production of nano-particles and nano-sheets. Using?N-methyl pyrrolidone (NMP) as a solvent, molybdenum diselenide (MoSe2) quantum dots can be prepared via chemical exfoliation - directly from molybdenum diselenide bulk powder. |
| Application | Having a?direct optical band gap of 1.48 eV with a photoluminescence peak at 840 nm, molybdenum diselenide monolayer?film?is?ideal for applications in optoelectronics. Also, with?with its narrower bandgap, higher optical absorbance and larger spin-splitting energy than MoS2,?MoSe2?ultrathin films?are potentially?better than MoS2 for the applications in tunnel FETs and optoelectronic devices. |
| Synthesis | High-quality molybdenum diselenide monolayer?film?was grown directly on the substrates (SiO2/Si) by the chemical vapour deposition (CVD) method. |
| Chemical Properties | gray powder(s); used as a solid lubricant and lubricant film prepared by sputtering 99.9% pure material [HAW93] [STR93] [CER91] |
| Uses | Molybdenum chalcogenide thin film transitors for solar cells are a rapidly expanding area of research and molybdenum selenide compounds play an important role in this research. The layered nature of MoSe2 gives rise to several interesting applications such as field effect transistors ; piezoelectrics and substrates for self assembly |
| Uses | Solid lubricant. |
| Definition | Available as a 40-micron powder. |
