Example Embodiment
[0017] Example 1
[0018] Weigh 1.7597g of europium oxide, then add 30ml of dilute nitric acid with a concentration of 4mol / L, stir for 30 minutes under heating, and after it is completely dissolved, prepare a 0.2mol / L europium nitrate solution.
[0019] Weigh 1.584g diammonium hydrogen phosphate and 1g cetyltrimethylammonium bromide into the beaker, measure 50ml of distilled water into the beaker and dissolve, adjust the pH value to 12 with 1mol / L NaOH solution ,为Solution 1. Weigh 2.109g of anhydrous calcium chloride into another beaker, add 25ml of distilled water to dissolve, use a pipette to measure 5ml of the prepared europium nitrate solution and add it to the beaker, which is solution 2. Then, the solution 2 was slowly added dropwise to the continuously stirring solution 1, and the mixed solution was heated to 100° C. and reacted for 6 hours. After the reaction is completed, the suspension is allowed to stand for 3 hours, and then the precipitate is washed 8 times with dis...
