Embodiment
Illustrate embodiments of the present invention following with particular specific embodiment, those skilled in the art can be by this explanation
Book disclosure of that understands advantage of the present invention and other effects easily.The present invention also can be by other different specific implementations
Example is implemented or applied, and the various details in this specification can also be directed to different viewpoints and application, without departing substantially from this hair
Bright spirit is lower to carry out various modifications and change.
It refer to Fig. 1 and Fig. 2.Fig. 1 is the side view of fluorescent material apparatus for coating of the present invention.Fig. 2 is phosphor of the present invention
Expect the top view of apparatus for coating.Fluorescent material apparatus for coating 100 of the present invention, which includes one, has a main inlet 114, a main discharge
Mouth 116, and the hollow cell body 110 that cell wall 112 is circular.The center of cell body 110 is provided with a dividing plate 120, and dividing plate separates cell body
Into the first groove 111 and the second groove 113.And the height of cell wall 112 is substantially higher than the height of demarcation strip 120, to facilitate technique to carry out.
Apparatus of the present invention 100 additionally comprise a fluorescent material injecting device 130, in manufacturing process, to inject fluorescence according to scheduled volume in order
Powder.
Fluorescent powder coating device 100 of the present invention, on cell wall 112 and more several auxiliary injection ports 115 and more can be provided with
Several auxiliary outlets 117, during fluorescent powder coating, to accelerate water filling or draining to accelerate the speed of processing in passing.This
Invention fluorescent powder coating, which is installed on fluorescent powder coating, which still needs, will be used cooperatively a limitation kickboard 150 with hollow space, and it is
One has the framework of closed housing, can bubble through the water column.
Fluorescent-powder coating method (refer to Fig. 3 A-3C) of the present invention, first by the base of required coating fluorescent material when implementing
The microscope carrier 140 that plate 142 is placed in the second groove 113, and limitation kickboard 150 is inserted in the first groove 111.Used in the present embodiment
Substrate 142 be a flip LED chip.Water is then injected into the first groove 111 and the second groove 113 through main inlet 114.Now,
Limitation kickboard 150 can float on the water surface of the first groove 111 because of water injection, and raise and raise with the water surface.To accelerate process speed, and can
So that water optionally is injected into two cell body (111,113) through auxiliary injection ports 115.Treat that water enters the first groove 111 not up to separation
During 120 height of plate, it can be mixed so that the fluorescent material to be coated with is slowly added dropwise into fluorescent material in water surface by fluorescent material injecting device 130
Solution is closed to inject the hollow space 160 of limitation kickboard 150 in the first groove 111.Fluorescent material floats on limitation kickboard after injection
The water surface of hollow space 160 in 150, it will not largely be spread in the outer water surface of limitation kickboard.
The fluorescent material in fluorescent material injecting device 130 used in the present embodiment is a fluorescent material solution, takes fluorescent material to do
For a fluorescent material, it for 500nm and material is SiO that the ball-type carrier of wherein fluorescent material, which uses particle diameter,2Nanosphere, and fluorescent powder
Then use particle diameter about 30nm Y2O3：La3+、YAG：La3+And CdSe：ZnS mixture, and fluorescent powder passes through silane point
Sub (APTMS) bond is in ball-type carrier surface.Fluorescent material is mixed in the ethanol with polymolecularity, a fluorescent material is obtained and mixes
Close solution.
Persistently inject water afterwards so that the liquid level of the first groove 111 and the second groove 113 continue to increase to higher than dividing plate 120. this
Shi Yinwei the first grooves 111 and the water surface of the second groove 113 are higher than dividing plate 120 with height, it is possible to utilize a limitation kickboard shifter
152 movements are surrounded by the limitation kickboard 150 of fluorescent material.By limitation kickboard 150 from the water surface movable of the first groove 111 to the second groove 113
The water surface.And the fluorescent material that kickboard 150 encases is limited, also just as the movement of limitation kickboard 150 smoothly moves to the water of the second groove 113
Face.Limitation kickboard shifter 152 used in the present embodiment, can be gripper or mechanical arm.
After the second groove 113 is moved into the limitation kickboard 150 of fluorescent material, then the water of the second groove 113 is independently discharged
Mouth 116 is discharged, to reduce the water surface of the second groove 113.When the water surface is reduced, the rough alignment institute of hollow space of kickboard 150 will be limited
The substrate 142 to be coated with., can be with stably equably by fluorescent powder coating in the upper surface of substrate 142 when the water surface reduces
And side surface.
Then, substrate 142 is placed in equipment for drying (not shown), the ethanol of tool polymolecularity is removed with evaporation
(not shown).It is to be dried completely after, then can obtain the surface of a substrate 142 has the substrate of fluorescent powder film.
The substrate for being coated with fluorescent material can use silicon alkoxide (such as：TEOS the aqueous solution) is molten as collosol and gel precursor
Liquid, and by by YAG and La3+Salt be dissolved in acid solution that a nitric acid is formulated it is well mixed after, with rotary coating
Mixed solution is coated on fluorescent powder film 21 by method, and forms a packed layer 22, and it is then to contain YAG: La that packed layer, which is made,3+'s
SiO2Material layer.After standing, the substrate 20 with fluorescent powder film 21 and packed layer 22 is heat-treated, then carries out at annealing
Reason, then complete the substrate for being coated with fluorescent material of the present embodiment.
This case will not be such that fluorescent material expands in large quantities because smoothly moving the fluorescent material bubbled through the water column using kickboard is limited
Dissipate, save material.And by water surface fluctuation control flow speed, cost is cheap and speed improvement, technique are simple, can be largely fast
Fast ground is by fluorescent powder coating in substrate.Fluorescent material smoothly declines by the limitation and the water surface of limitation kickboard, can be equably
It is coated on substrate surface.
