Tb3+/Eu3+ZnGa2O4　glass　ceramics　were　synthesized　by　sol-gel　method.　The　influence　of　heat　treatment　temperature　on　the　micro-structure　of　the　glass　ceramic,　and　the　luminescence　properties　of　samples　doped　with　different　rare-earth　ions　were　studied.　The　results　show　that　the　precipitation　of　spinel　ZnGa2O4　nano-crystals　among　the　glassy　matrix　after　the　dry　gel　heat-treated　at　the　temperatures　in　the　range　from　800　to　900　.　Unfortunately,　the　glass　ceramic　heat-treated　at　1000　was　opaque　due　to　the　crystallization　of　the　glassy　matrix　with　the　precipitation　of　trigonal　Zn2SiO4　and　hexagonal　SiO2.　The　energy　transfer　from　the　ZnGa2O4　nano-crystals　to　the　doped　Tb3+　and　Eu3+　in　the　glass　ceramic　was　proved　by　the　photoluminescence　excitation　spectra.　The　green　and　the　red　emission　from　Tb3+　and　Eu3+　respectively　were　observed　in　the　Tb3+/Eu3+ZnGa2O4　glass　ceramic　heat-treated　at　900　,　which　combined　with　the　blue　emission　from　ZnGa2O4　nano-crystals　to　realize　the　while　emission　in　the　glass　ceramic.
