Oddělení tenkých vrstev a nanostruktur
In this talk, which is a public rehearsal of my PhD defense, I will present the main results of my doctoral work. First, I will discuss the origin of a fast blue-green luminescence band in silicon nanocrystals which was investigated by means of time-resolved spectroscopy at low helium temperatures. Second, I will give a brief introduction to the phenomenon of light extraction employing leaky modes of photonic crystals. Third, results of light extraction enhancement from two-dimensional photonic crystals prepared on a nanocrystalline diamond layer and on a silica layer with embedded silicon nanocrystals will be discussed.
