Embodiment 1
[0035] 1) Steps to prepare the gel
[0036] First, the raw material CaCO 3 、Eu 2 o 3 、 Bi 2 o 3 , Li 2 CO 3 and H 3 BO 3 Put in a large beaker and add HNO 3 Allow to dissolve until clear and add H in hot water 3 BO 3 Prepare the inorganic solution,
[0037] Thereafter, pour ethanol into the Si(OC 2 h 3 ) 4 Prepare an organic solution in , and add CH equivalent to 10% of the volume of the organic solution 3 COOH is used as a stabilizer, where Si(OC 2 h 3 ) 4 The volume ratio with ethanol is 1:1,
[0038]Then, slowly pour the inorganic solution into the organic solution, use nitric acid as a catalyst and adjust the pH value of the solution to about 2 with nitric acid, stir in a water bath at 75°C for 90 minutes to prepare a gel,
[0039] wherein, the gel contains 15mol% CaCO 3 ; 60mol% Si(OC 2 h 3 ) 4 ; 25 mol% B 2 o 3 ;9 mol% Eu 2 o 3 ; 2 mol% Bi 2 o 3 and 11 mol% Li 2 CO 3 .
