Abstract
The aim of the present study was to determine the influence of doping rare earth ion on strontium calcium aluminate (CaO–SrO–SiO2–Al2O3). Therefore, the authors have manufactured luminescent material consisting of 40CaO–5SrO–5SiO2–50Al2O3 doped with Dy3+. The compositions have been selected on the basis of chemical stability. Five pellets were prepared with different calcination temperatures and times, namely 400 and 600°C for 1 and 2 h, in order to shed light on their luminescence behaviour. X-ray diffraction, energy dispersive X-ray analysis and scanning electron microscopy elaborate and characterise the formation of small particle of photoluminescent material in the phosphor matrix host material.
