Abstract

Two-dimensional colloidal nanocrystals have recently revealed a great potential as optical gain media due to their remarkable optical properties. Various optoelectronic devices designed for CdSe nanoplatelets have been already introduced, such as hybrid light emitting diode and vertical cavity laser. So far these devices cover only visible spectra because they use NPLs with thicknesses of 5 monolayers or more, which optical properties are well known. We believe that ultrathin NPLs consisting of only 4 ML will show optical properties more than favorable for their use as optical gain media, providing endless opportunities for creating pure-colored light emitters for UV wavelengths. Here we have synthesized NPLs of both 5 ML and 4 ML thicknesses, studied and compared their optical properties meaning to prove that possibility.
