Abstract

The low quantum yield (∼10^-5) has restricted practical use of photoluminescence (PL) from MoS₂ composed of a few layers, but the quantum confinement effects across two-dimensional planes are believed to be able to boost the PL intensity. In this work, PL from 2 to 9 nm MoS₂ quantum dots (QDs) is excluded from the solvent and the absorption and PL spectra are shown to be consistent with the size distribution. PL from MoS₂ QDs is also found to be sensitive to aggregation due to the size effect.
