We study the time-resolved resonant secondary emission spectra of CuCl quantum dots in a NaCl matrix under two-photon excitation. The emission is clearly decomposed into the luminescence and scattering components by means of their temporal behavior. By analyzing the obtained results, we show that th
A theoretical study is made of the possible occurrence of exciton-enhanced secondary emission in insulators containing donor levels. It is assumed that the primary beam produces, besides secondary electrons, excitons; the latter may ionize donors and thereby enhance the secondary yield. The discussi
