Abstract

The invention discloses use of a uranium-containing compound as a scintillator. The uranium-containing compound is a uranium-containing organic-inorganic hybrid compound or a uranium-containing inorganic compound. The uranium-containing organic-inorganic hybrid compound is a uranium-containing organic carboxylate or a uranium-containing organophosphate. The uranium-containing inorganic compound is a uranium-containing non-metallate, a uranium-containing metal salt, or a uranium-containing halide. The invention discloses the uranium-containing organic-inorganic compound or the uranium-containing inorganic compound having intrinsic scintillating ability, and provides a new concept and method for the development of (organic-inorganic, inorganic) scintillators of various chemical compositions and configurations with the uranium element.

First claim

and
the uranium-containing inorganic compound is a uranium-containing non-metallate of Formula (III), or a uranium-containing metal salt of Formula (IV):

in which m is 1 or 2, and n is for 2;
in Formula (I), R 1 is selected from phenyl, substituted phenyl, or alkyl;
in Formula (II), R 2 is selected from phenyl, substituted phenyl or alkyl;
in Formula (III), M is selected from the B, N, Si, Se, P, As, S or Te element;
in Formula (IV), Y is selected from the Mo, V, Cr, Nb, W, Re, Ga, Ge, Sb or Sn element; and
in Formulas (II), (III) and (IV), A n+ is independently selected from tetramethylammonium cation, Na + , K + , NH 4 + , Rb + , Cs + , Mg 2+ , Ca 2+ , Sr 2+ , Ba 2+ , Pb 2+ or Bi 2+ .

2. The scintillator as claimed in claim 1 , wherein R 1 is phenyl or alkyl.

3. The scintillator as claimed in claim 2 , wherein in Formula (I), the uranium-containing organic carboxylate is UO 2 (C 9 O 6 H 4 )(H 2 O), and the Formula (I) is a structural formula of:

4. The scintillator as claimed in claim 3 , wherein the UO 2 (C 9 O 6 H 4 )(H 2 O) is prepared by steps of:
dissolving uranyl nitrate, boric acid, and 1, 3, 5-benzenetricarboxylic acid in water, sealing, and performing reaction at 190-250° C., cooling and washing the resulting solution to obtain the UO 2 (C 9 O 6 H 4 )(H 2 O).

5. The scintillator as claimed in claim 4 , wherein a molar ratio of uranyl nitrate, boric acid, and 1, 3, 5-benzenetricarboxylic acid is 0.8-1:1-10:1-2.

6. The scintillator as claimed in claim 1 , wherein in Formula (II), n is 1, R 2 is phenyl, and A n+ is tetramethylammonium cation.

7. The scintillator as claimed in claim 6 , wherein in Formula (II), the uranium-containing organophosphate has a structural formula of

8. The scintillator as claimed in claim 1 , wherein in Formula (III), n is 1, M is the B element, and A n+ is Na + .
