SCINTILLATORS FOR DETECTORS IONIZING RADIATION SYNTHESIZED BY SOL-GEL METHOD

Scintillators are made by melting multicomponent systems using sol-gel technology. Sol-gel matrices are cheap to manufacture, do not require additional machining (grinding, polishing), it is possible to easily vary the size and shape of the final product. At the same time, sol-gel matrices have a wide range of transparency, have high mechanical strength, and are chemically stable. The emission has maximum at 615-620 nm.

The light output of scintillations for the proposed inorganic scintillator (Eu3+: Y) is 1.5 times higher than for the known composition CaGa2S4:Eu2+. Additional advantages of the obtained inorganic scintillator are its increased sensitivity, versatility and selectivity of recording corpuscular radiation.

FIELD OF APPLICATION:

For using in nuclear medicine for detecting and localizing tumor formations and metastases, antitumor therapy.

MAIN BENEFITS:

  • Low cost;
  • Glass is formed after heat treatment at temperatures of 800-900 °С;
  • Inorganic matrix and doping complexes
  • Wide range of transparency;
  • Mechanical and chemical resistance;
  • High light output of scintillations (1.5 times higher than for the known composition CaGa2S4:Eu2+);
  • Energy-saving technology and standard equipment.
