Abstract

A recent publication by Shin et al. [Opt. Express 25, A113 (2017)] contains an optical simulation model for the quantum dots (QDs) nanophosphor based on the mean free path concept. We show that their measured scattering pattern of QDs is misleading, which would result in a fatal deviation between simulated and actual values.
