Abstract：

Transparent　bulk　glass-ceramics　of　Eu3+　doped　ZnAl2O4/SiO2　(ZAS)　were　synthesized　by　sol-gel　method.　The　influence　of　Eu3+　concentration　and　heat-treated　temperatures　on　the　luminescence　of　ZAS∶Eu3+　glass-ceramics　were　studied　by　X-ray　diffraction　(XRD),　transmission　electron　microscopy　(TEM),　and　photoluminescence　(PL)　spectra.　The　results　show　that　ZAS∶　Eu3+　emits　intense　red　emission　with　a　maximum　at　611　nm　originating　from　the　5D0→7F2　transition　of　Eu3+.　The　emission　intensity　increases　with　increasing　Eu3+　concentration　and　it　reaches　the　maximum　when　the　doping　level　is　20　mol%,　but　concentration　quenching　behavior　has　been　observed.　When　the　heat-treated　temperature　is　900℃,　the　luminescence　intensity　is　optimal,　and　a　high　temperature　quenching　effect　occurs　as　heat-treated　temperature　increases.　The　excellent　Commission　International　de　I＇Eclairage　(CIE)　chromaticity　coordinates　indicates　that　ZAS∶0.20Eu3+　glass-ceramic　is　a　good　material　for　red　color　display.　©,　2015,　Rengong　Jingti　Xuebao/Journal　of　Synthetic　Crystals.　All　right　reserved.
