centers at Tann.> 400℃ and complete absence of PhL at
Tann.> 500℃ are observed due to the delete of hydride
SiH-bonds on the porous surface; 6) long excitation of
PL leads to heating that transforms of hydride complexes.
This fact confirms, that the light emitting centers are
formed due to hydride coverages of surface NCs por-Si;
7) a nnealing at Tann = 8 00℃ of por-Si on air leads to the
formation of light-emitting centers in the form of oxides
of silicon.
