The temperature-dependent luminescence behavior of three ordered langasites La3Ga5ZrO14 (LGZr), La3Ga5HfO14 (LGHf) and La3Ga5SnO14 (LGSn) doped with up to 20% Eu3+ were investigated. Band gap energies of 4.32 eV (LGZr), 4.43 eV (LGHf), and 4.46 eV (L

Lu3Al5O12:Ce3+ (LuAG:Ce) is a scintillator with a fast response time. The light yield is lower than theoretically expected and to increase the light yield co-doping with Pr3+ is investigated. To better understand the energy flow to the Ce3+ ion, firs

Y 2 SiO 5 doped with Ce 3+ was successfully prepared at 1300 °C with the aid of Li 2 SO 4 flux. SEM and TEM images proved that the sizes of particles making-up the powder are in the range of 1–10 μm. A small fraction of grains is nanosized. EDS s
