Fluorescent powder composition capable of promoting rapid growth of algae and application thereof

[0032] Example 1

[0033] According to (y) 1-x CE x ) 3 Al 5 O 12 The molecular formula of the phosphor, referring to each oxide, and add 5% BAF of the total weight of the oxide. 2 After mixing evenly with an agate mortar, it was placed in a rigid jade crucible, and the temperature of 1580 ° C and a hydrogen concentration of 75% was held in the reduced furnace of a resolution gas for 5 hours. After cooling, the yellow phosphor y, the yellow phosphor Y is excited under 450 nm blue, such as figure 1 Indicated.

[0036] Example 2

[0037] In accordance with (CA 1-Y SR Y Alsin 3 : 0.015EU 2+ The molecular formula of the phosphor is measured in the glove box, and each oxide is improved in the glove box and mixed with an agate mortar. It is placed in a molybdenum crucible, placed in a nitrogen atmosphere carbon tube furnace in a pressure of 0.6 MPa. 5 hours. . After cooling, removed the red phosphor R1, the red phosphor R1, the emission spectrum of 450 nm blue is excited, figure 2 Indicated.

[0040] Example 3

[0041] In accordance with (Al 1-c GA c ) 2 O 3 : ZCR 3+ The molecular formula of the phosphor, referring to the formulation of alumina, gallium oxide, and chromium oxide, and placed in a superfolder, added to the super mixer, and adding the total weight of 5% by the ovens. 2 As the flux mixing 5-10 min, then pour the mixed material into the corundum, placed in the muffle furnace, and heat the temperature below 5 ° C / min after 5 hours, then remove, remove it, with pure water Cleaning to the conductivity of less than 10 sus of 10 el of 10 us / cm, and then dried after dehydration, it was rubbed, that is, the ruby ​​phosphor R2 was obtained. Its excitation and emission spectrum image 3 Down, Cr 3+ When the concentration is 1%, the XRD map of different C-value series ruby ​​phosphor R2 is like Figure 4 As shown, the results shown in the figure showed that the Ruby phosphor R2 was successfully prepared in the middle of the in Example 3. When the ruby ​​phosphor R2 is expressed in Al 2 O 3 : ZCR 3+ When Cr 3+ The effect of concentration on the intensity of R2 emission light Figure 5 As shown in the figure, the results show that when Cr 3+ When the concentration is 1%, the fluorescent powder is the highest. CR 3+ When the concentration is 1%, GA 3+ Effect of concentration changes on the peak of rubble phosphor R2 Figure 6 As shown, showing the GA 3+ The concentration change, the R2 emission peak occurs blue. The prepared ruby ​​phosphor R2 SEM map such as Figure 7 Indicated.
