Description
Technical field
The invention belongs to luminescent material technical fields, and in particular to a kind of preparation method of zinc doping Luetcium aluminum garnet.
Background technology
Lu2O3-Al2O3System is with Y2O3-Al2O3Grow up based on system.Due to Y2O3-Al2O3It is deposited in system
In such as YAG (yttrium-aluminium-garnet, Y3Al5O12) and YAP (yttrium aluminate, YAlO3) both phases, since they have good materialization
Property and optical property become most common host material.People are prepared by adulterating the active ions such as Nd, Yb and Ce
High performance laser or scintillation material.Such as common Nd：YAG and Yb：YAG laser crystal, Ce：YAP scintillation crystals.People at present
Also Ce is being had studied：YAG and Yb：The scintillation properties of YAG.But with the development of science and technology, YAP and YAG is relatively low due to density
And cascade unit is larger, cannot be satisfied the requirement of minimonitor, therefore people Lu3+Ion replaces Y3+Ion obtains Lu2O3-
Al2O3System.Research finds such as to mix Cerium aluminate lutetium (i.e. Ce：LuAlO3) scintillation crystal density up to 8.34g/cm3, it is people
One of highest material of density in the medical scintillator studied.And with reference to the sudden strain of a muscle of the active ions YAG crystal such as doping Yb and Ce
Bright and laser activity development, has important role to the preparation of lutetium aluminum carbuncle crystal in practical application.
Relevant research domestic at present be mainly silicate silicic acid lutetium crystalline ceramics preparation, though achieve relatively
High transparency, but refraction and absorption due to the crystal boundary of polycrystalline structure ceramic body to light, optical characteristics come relative to crystal
Say or have larger gap.And domestic related crystalline research then concentrates on the growth of lutetium aluminate crystal, but due to Lu2O3-
Al2O3System exists simultaneously three kinds of phases, and aluminic acid lutetium is mutually a kind of high-temperature stable phase, and compares and belong to thermodynamics at room temperature not
Stable phase, is usually easy to be formed other phases in growth and is difficult to grow large-size crystals, and be easy to crack.

Face organic impurities removal, while can utilize clutch that can be thoroughly mixed solid, obtain mixture；
Alundum (Al2O3) and three oxidation two lutetiums acidifications are formed acid solution, while three two lutetiums of oxidation are converted into lutetium by step 2
Ion, alundum (Al2O3) are converted into aluminium ion, by the mixing of ionic nature, to increase phase mixcibility of the lutetium with aluminium.
Step 3 is added zinc chloride as soluble dopant into solution, plays Ar ion mixing doping effect, adopts simultaneously
It uses hydroxypropyl cellulose to be added as dispersant into mixed liquor, promotes the dispersibility and toughness of solution.
Step 4 can form aeration reaction by the aeration reaction of carbon dioxide, and metal ion is formed carbonic acid precipitation, and
And using hydroxypropyl cellulose dispersibility and precipitation itself porosity, formed mixing package, be passed through ammonia adjust pH until
It is in alkalinity completely, finally by the mode of ultrasound filtration by Precipitation, while ultrasound can utilize clutch that can will wrap up property
Precipitation smash again, carry out depth mixing, additionally it is possible to reduce washing difficulty；Absolute ethyl alcohol washing can be by hydroxypropyl cellulose
Dissolving removal, and precipitation is not destroyed, while dissolved hydroxypropyl cellulose can recycle reuse.
Step 5 converts carbonate to oxide, and the effect being thoroughly mixed using it by the way of freeze-day with constant temperature,
Being sufficiently mixed for oxide can be formed, ball mill grinding calcines to form zinc doping Luetcium aluminum garnet.
