Motivation

We use a home-built confocal microscope to characterize single quantum chromophore systems, such as colloidal semiconductor nanostructures, also referred to as quantum dots. At room temperature we measure the photoluminescence rate, the number of pho-tons, as a function of spatial position. More-over we acquire the temporal evolution of the photon stream of each individual nanostruc-ture in order to extract the photoluminescence lifetime of the excited state at room tempera-ture. Those nanostructures do have the poten-tial to act as single photon sources at room temperature opening a novel pathway for a secure information transfer technology based on single photon streams.

Your task

You will face the challenge to add to our detec-tion work horse an extension that enables wave-length selective confocal microscopy and spec-troscopy. Moreover you will manage to learn in depth skills on 4D microscopy (x,y,z,t) and corre-lation analysis. Pending on your academic goal (bachelor, master, diploma) the working load and the final success level will be scaled accordingly.

Qualification

Having heart about lasers, optical microscopes and nano structures might help.
