The fluorescence of two divalent europium-activated oxonitridoaluminosilicates, namely SrSi5AlO2N7 and SrSiAl2O3N2, is reported in this work. The powder sample was synthesized by sintering at 1800°C (SrSi5AlO2N7) or 1600°C (SrSiAl2O3N2) for 2 h under 0.5 MPa N2. A single broadband blue-green emission is observed for both SrSi5AlO2N7 : Eu2+ and SrSiAl2O3N2 : Eu2+ at room temperature under ultraviolet excitation. The short-wavelength fluorescence is attributed to the weak crystal-field strength as a result of long distances between the activator ion and ligand anions. The effect of the Eu2+ concentration on the emission intensity and CIE chromaticity coordinations of both samples is presented.<br>
