Luminescence properties of the inorganic liquids based on SOCl2-GaCl3 activated by neodymium in the presence of uranyl under excitation by nuclear reaction products

The luminescence properties of the inorganic liquids SOCl2-CaCl3-Nd3+-UO22+ under excitation by the products of the nuclear reactions in the flow of the fast neutrons are investigated. The luminescence photon number distributions in depending on the time or the wavelength are measured by means of the statistical method of the own-photon spectrometry. There is calculated the contribution energy speed of charged particles emerging in the bulk specimen as a result of neutron interaction with matter. The efficiency η of charged particles energy conversion to luminescence energy has been assessed quantitatively. It is shown, that the presence of UO22+ leaded to the decrease as the luminescence lifetime of 4F3/2-level as the value of η. 4 refs.; 2 figs.; 1 tab
