Vp. Oleshko et al., OBSERVATION OF EXCITON-STATES IN SILVER-HALIDE NANOPARTICLES BY CRYOELECTRON SPECTROSCOPIC IMAGING AND ELECTRON-ENERGY-LOSS SPECTROSCOPY, Mendeleev communications, (6), 1997, pp. 213-215
Electron excitations in Ag(Br,I) nanocrystals (attributed to excitons
and plasmons possibly superimposed on interband transitions) and many-
electron effects have been observed for the first time by cryo-electro
n spectroscopic imaging and electron energy-loss spectroscopy.
