Gn. Dudkin et al., A TECHNIQUE AND RESULTS OF A STUDY OF INORGANIC SCINTILLATING MATERIALS, Instruments and experimental techniques, 39(2), 1996, pp. 186-190
A procedure for measuring the temporal characteristics and light outpu
t of powdered scintillators excited by delta, gamma-, and alpha-partic
les from radioactive sources is described. Results of measurements of
characteristics are presented for similar to 40 scintillating compound
s including cerium-doped yttrium silicate and scandium berate; europiu
m-doped strontium phosphate; cerium-doped strontium silicate, calcium
silicate and magnesium calcium silicate; etc. Upon beta- and gamma-exc
itation, cerium-doped scandium borate gives the highest light output w
ith a fluorescent lifetime of 40 +/- 4 ns. The highest light output fo
r alpha-excitation was from cerium-doped yttrium aluminum perovskite,
with a fluorescent lifetime of 29 +/- 3 ns.
