| Abstract: | A method for the hydrothermal synthesis of bismuth germanium oxide
comprises dissolving a bismuth precursor (e.g., bismuth nitrate
pentahydrate) and a germanium precursor (e.g., germanium dioxide) in
water and heating the aqueous solution to an elevated reaction
temperature for a length of time sufficient to produce the eulytite phase
of bismuth germanium oxide (E-BGO) with high yield. The E-BGO produced
can be used as a scintillator material. For example, the air stability
and radioluminescence response suggest that the E-BGO can be employed for
medical applications. |
