Embodiment 1
[0031] A method for preparing a rare earth / Schiff base SBA-15 type mesoporous composite luminescent material, which specifically includes the following steps:
[0032] (1) Configuration of terbium nitrate ethanol solution:
[0033] Put 1.87g of terbium oxide into a beaker, add 10-20ml of concentrated nitric acid and 5-10ml of hydrogen peroxide, then heat and evaporate to obtain solid terbium nitrate, then dissolve the obtained solid terbium nitrate in absolute ethanol, and use absolute ethanol to volume to 100 mL to obtain a terbium nitrate ethanol solution with a concentration of 0.1mol / L;
[0034] (2) Preparation of hybrid material precursor:
[0035] Dissolve 0.536g (2mmol) of N,N'-disalicylaldehyde ethylenediamine (Salen) in 20ml of absolute ethanol at a controlled temperature of 65°C to obtain N,N'-disalicylaldehyde ethylenediamine Amine ethanol solution;
[0036] Pour the resulting N,N'-disalicylaldehyde ethylenediamine ethanol solution into a three-necked flask, and ...
