Abstract: Pure Gd3Al5O12:Eu3+ crystalline phase was formed at 900℃ with the precursor prepared by nitric-citric combustion.The luminescent properties of Gd3Al5O12:Eu3+ was also described,and the emission of Gd3Al5O12:Eu3+ at 615 nm and 593 nm was considered to be the Eu3+ 5D0-7F2 and Eu3+ 5D0-7F2 transition.The Synthesis process was reported in details,related to the pH value,citric acid/metal ion and calcinations temperature.

Key words: gadolinium-aluminum garnet, europium, citrate-nitrate combustion, luminescence
