Phosphor materials are of special interest due to their important applications ranging from solid state lightning and displays to biomedicine. Understanding the spectroscopic properties of these materials is important for optimizing their emission for technological applications. Zinc silicate (Zn2SiO4) has been identified as a very suitable host matrix for many rare-earth and transition metal dopant ions with excellent luminescent properties in the blue, green and red spectral zones. Here, we present high resolution measurements of low-temperature photoluminescence of trivalent europium doped zinc silicate particles prepared by combination of so-gel and combustion synthesis route. We observed and analyzed 5D(0) - GT F-7(J) spin forbidden f-f electronic transitions at low temperatures, as well as emission kinetics from D-5(0) level and lifetime-temperature dependence.
