Pk. Kashkarov et al., INFLUENCE OF AMBIENT DIELECTRIC-PROPERTIES ON THE LUMINESCENCE IN QUANTUM WIRES OF POROUS SILICON, PHYSICS OF LOW-DIMENSIONAL STRUCTURES, 1-2, 1997, pp. 123-129
The photoluminescence spectra of porous silicon with pores filled by b
enzol, acetone, ethanol and methanol molecules have been investigated.
The photoluminescence quenching caused by adsorption is found to incr
ease for ambients with higher dielectric constants. The discussion of
the results is based on the model of radiative recombination of excito
ns in silicon nanostructures.
