In this paper, we focus on the investigation of crystallization in the sodium- and potassium-zinc-silicate system and the photoluminescence properties of Er3+-doped glass-ceramic materials. It was found that the presence of Na2O promotes the crystallization of Zn2SiO4 resulting in non-transparent glass-ceramic material at 750 degrees C, whereas the K2O-ZnO-SiO2 material remained transparent in the entire heat treatment range. Nevertheless, the crystallization of ZnO and Zn2SiO4 leads to an increase of photoluminescence intensity of Er3+ ions by up to 300 % compared to the pre-cursor glass. The Stark-splitting of the Er3+ emission spectra at 1.5 mu m after 978 nm excitation as well as shortening of the fluorescence lifetime suggest the incorporation of Er3+ ions inside the highly symmetric environment of ZnO and Zn2SiO4.
