Example Embodiment
[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.

Example Embodiment
[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 R...

Abstract
The invention discloses a fluorescent powder composition capable of promoting rapid growth of algae and application thereof, which is characterized in that (Y<1-x>Cex)3Al5O12 fluorescent powder, Ca<1-y>SryAlSiN3: 0.015Eu<2+> fluorescent powder and (Al<1-c>Gac)2O3: zCr<3+> fluorescent powder are mixed according to a certain proportion, and after the mixed powder is excited by 420-480nm blue light,the fluorescent powder Ca<1-y>SryAlSiN3: 0.015Eu<2+> emits red light with a main peak wavelength of 645-660 nm, green light emitted by the fluorescent powder (Y<1-x>Cex)3Al5O12 is just absorbed by thefluorescent powder (Al<1-c>Gac)2O3: zCr<3+>, dark red light with the wavelength of 680-693 nm is emitted, and finally, the fluorescent powder combination emits a combined spectrum with the main peakwavelengths of 645-660 nm and 680-693 nm, so that very strong dark red emission is generated, and a light conversion effect is achieved. According to the fluorescent powder combination, green light which cannot be absorbed by chlorophyll in single fluorescent powder (Y<1-x>Cex)3Al5O12, Ca<1-y>SryAlSiN3: 0.015Eu<2+> and (Al<1-c>Gac)2O3: zCr<3+> is converted into dark red light which has remarkableinfluence on plant photosynthesis and photoperiod effect, the light energy utilization rate of algae can be remarkably increased when the fluorescent powder combination is prepared into a lamp bead ora light supplementing lamp to irradiate the algae, and the growth of the algae is promoted.
Description
technical field [0001] The invention belongs to the technical field of growth regulation of algae plants, and relates to a fluorescent powder combination that can promote the rapid growth of algae plants, and also relates to an application method of the fluorescent powder combination. Background technique [0002] Most algal plants live in water, with simple structure, no differentiation of roots, stems, and leaves, and cells containing chloroplasts, such as Chlorella, Chlorella, a genus of single-celled green algae of the Chlorella phylum, is a spherical single-celled freshwater Algae; Chlamydomonas is a single-celled algal plant with a cup-shaped chloroplast in the cell; Spirogyra is a multi-cellular algal plant with ribbon-shaped chloroplasts in the body; kelp and Gemweed have spindle-shaped chloroplasts in the body. However, some prokaryotic algae such as cyanobacteria do not form a double-membrane-coated structure in their cells, and the structure carrying chlorophyll i...
