M. Luccoborlera et al., STUDY OF DEFECTS IN NASICON COMPOUNDS BY THERMOLUMINESCENCE EXPERIMENTS, Nuovo cimento della Societa italiana di fisica. D, Condensed matter,atomic, molecular and chemical physics, biophysics, 19(7), 1997, pp. 949-953
Samples of Nasicon compounds with different silicon and phosphorus con
tents were investigated with spectrally resolved thermoluminescence. E
vidence of the presence of charged point defects originated by exchang
es of silicon and phosphorus ions lying in different cells was obtaine
d. Other defects are ascribed to displacements of sodium ions in unocc
upied sites.
