Abstract
We discuss a promising solid-state system that emits single photons at room temperature in the blue–green range, making it an attractive candidate for quantum communications in free space and underwater. The active element is a core-shell ZnSe tapered nanowire embedding a single CdSe quantum dot grown by molecular beam epitaxy. A patterned substrate enables a comprehensive study of a single nanowire using various methods. Our source shows potential for achieving a total brightness of 0.17 photon per pulse and anti-bunching with g(2)(0) < 0.3 within a restricted spectral window. Additionally, we analyze the impact of charged excitons on the g(2)(0) value in different spectral ranges.
