Embodiment 1

[0060] x=0, y=0, z=0, the BaCO 3 , NH 4 h 2 PO 4 、H 3 BO 3 Weigh according to the above proportion, mix evenly, and pre-fire at 800°C for 1 hour to remove moisture, carbon dioxide and ammonia in the raw material of the mixture. After grinding evenly with NaF flux (the distribution ratio of each component is Ba 3 BP 3 o 12 :B 2 o 3 :P 2 o 5 :NaF=1:1:1:3), put them into a platinum crucible together, heat up and melt to prepare for growth. The rotational speed of the seed crystal was 5 rpm. Adjust the appropriate crystal inoculation temperature. When the seed crystal on the seed rod just contacts the melt, keep the position of the seed crystal unchanged, and start to slowly cool down (cooling rate = 0.1°C / hour). After growing the crystal, lift the crystal to make it Detach from the melt surface, and anneal at a position about 1cm away from the liquid surface to eliminate thermal stress. Then slowly cool down to room temperature, and take out the crystals. The cryst...

Embodiment 2

[0062] x=0.010, y=0, z=0, the BaCO 3 , (NH 4 ) 2 HPO 4 , B 2 o 3 、Eu 2 o 3 Weigh according to the above proportion, mix evenly, and pre-calcine at 450°C for 9 hours to remove moisture, carbon dioxide and ammonia in the raw material of the mixture. After grinding evenly with NaF flux (the distribution ratio of each component is Ba 3 BP 3 o 12 :B 2 o 3 :P 2 o 5 :NaF=1:1:1:3), put them into a platinum crucible together, heat up and melt to prepare for growth. The rotational speed of the seed crystal was 5 rpm. Adjust the appropriate crystal inoculation temperature. When the seed crystal on the seed rod just contacts the melt, keep the position of the seed crystal unchanged, and start to slowly cool down (cooling rate = 0.05°C / hour). After growing the crystal, lift the crystal to make it Detach from the melt surface, and anneal at a position about 1cm away from the liquid surface to eliminate thermal stress. Then slowly cool down to room temperature, and take out t...

Embodiment 3

[0064] Repeat the method of Example 2 according to the content of each component and the crystal growth parameter specified in the following table 1 to obtain Ba 3 BP 3 o 12 :Nd 3+ (1%), Na + (1%) crystals. Crystal powder XRD pattern see figure 1 (c).

Abstract

The invention relates to a Ba3BP3O12 crystalloid, a growing method and the application thereof, belonging to the field of crystalloid growth. The Ba3BP3O12 crystalloid of the invention has the chemical formula composition of Ba (1-x-2y-2z) M (X) M (y)A (y) M (Z) 3 BP3O12, wherein, x, y and z are less than or equal to 0.35 and more than or equal to 0; M is one ion or a plurality of ions in Sr, Ca, Mg, Be, Zn, Eu, Mn and Yb which have +2 valent state; the M is one ion or a plurality of ions in Cr, Bi, Ti, Ce, Pr, Nd, Sm, Eu, Dy, Ho, Er, Tm and Yb which have +3 valent state; A is one ion or a plurality of ions in Li, Na, K, Rb and Cs; and M is one ion or a plurality of ions in Cr, Ti, Zr and Hf which have +4 valent state. The crystalloid produced by a flux growth method has the advantages of great hardness, good mechanical property, difficult cracking and deliquescence, easy processing and storing and the like, so as to be applied to the fields such as laser crystal, acousto-optic crystal, photorefractive crystal or photonic crystal.

Description

technical field [0001] The present invention relates to a Ba 3 BP 3 o 12 A crystal and its growth method and application belong to the field of crystal growth. Background technique [0002] In recent years, borates (such as β-BaB 2 o 4 , LiB 3 o 5 , NdAl 3 (BO 3 ) 4 , KBe 2 BO 3 f 2 etc.) and phosphates (such as KTiOPO 4 ) and other crystals have obtained important applications in the fields of laser, nonlinear optics and electro-optic, showing huge economic and social benefits. At present, borophosphates with boroxy groups and phosphooxy groups as basic structural units have gradually attracted attention, and a series of borophosphate compounds have been studied and synthesized. The Eu-doped 2+ Ionic barium borophosphate (Ba 3 BP 3 o 12 :Eu 2+ ) powder material is a kind of high luminous intensity (luminous intensity can be compared with BGO), luminous peak position matches with photomultiplier tube (440 / 510nm), short decay time (20ns decay component acco...
