Embodiment 1
[0032] Preparation of [Ca 0.84 CO 3 : 0.08Eu 3+ , 0.08K + ]
[0033] Take CaCl 2 (A.R) particles 42mmol (4.62g) into the grinding equipment to grind into powder, and then pipette to take 4ml (1mmol / ml) Eu(NO 3 ) 3 Pour the solution into the grinding equipment, grind and mix thoroughly to make the CaCl 2 The powder is completely dissolved, and then the weighed 48mmol (6.64g) K 2 CO 3 Add the powder into the solution little by little, and grind while adding. If the mixture is sticky at the moment, there is no need to add deionized water. If the viscosity is too high, add a small amount of deionized water to facilitate grinding and reaction, and continue grinding and mixing for 30 minutes. -45 minutes, then stand at 32°C for 4 hours, then move the mixture to an oven and dry at 110°C for 3-5 hours, grind the dried mixture into powder, then wash with deionized water, and then filter, Fluorescent products can be obtained after drying.
Embodiment 2
[0035] Preparation of [Ca 0.92 CO 3 : 0.04Eu 3+ , 0.04K + ]
[0036] Take 1mmol (0.352g) Eu 2 o 3 Put it in an enamel container, then add a small amount of dilute nitric acid and stir until Eu 2 o3 Dissolve completely, then add the weighed 46mmol (11.18g) Ca(ClO 3 ) 2 2H 2 O is dissolved and mixed in the above solution. After transferring the above solution to the grinding equipment, add 49mmol (6.77g) K little by little 2 CO 3 , grinding and mixing while adding, if the mixture is sticky at the moment, there is no need to add deionized water, if the viscosity is too high, you can add a small amount of deionized water to facilitate grinding and reaction, continue grinding and mixing for 30-45 minutes, then at 32 ° C Let it stand for 4 hours, then move the mixture to an oven and dry at 110°C for 3-5 hours, grind the dried mixture into powder, wash with deionized water, filter and dry to obtain the fluorescent product.
Embodiment 3
[0038] Preparation of [Ca 0.76 CO 3 : 0.12Eu 3+ , 0.12K + ]
[0039] Take CaCl 2 (A.R) particles 38mmol (4.18g) were put into the grinding equipment and ground into powder, and 6ml of deionized water was added to dissolve the CaCl 2 The powder was dissolved, then 6mmol (2.20g) EuCl was added 3 ·6H 2 O, ground and mixed to dissolve it in the above solution, and then weighed 47mmol (6.50g) K 2 CO 3 Add to the solution little by little, grind and mix while adding, if the mixture is sticky at the moment, no need to add deionized water, if the viscosity is too high, add a small amount of deionized water to facilitate grinding and reaction, and continue to grind and mix for 30 -45 minutes, then stand at 32°C for 4 hours, then move the mixture to an oven and dry at 110°C for 3-5 hours, grind the dried mixture into powder, then wash with deionized water, and then filter, Fluorescent products can be obtained after drying.
