Abstract
Thermal SiO2 films have been implanted with Si+ ions using double-ener gy implants (200 + 100 keV) at a substrate temperature of about -20 de grees C to total doses in the range 1.6 x 10(16)-1.6 x 10(17) cm(-2) f ollowed by short-time thermal processing, in order to form a Si nanost ructure capable of yielding blue photoluminescence (PL). The intensity and the peak position of the PL band have been investigated as a func tion of ion dose, manner of heat treatment, anneal time and anneal tem perature. For the formation of blue PL emitting centres, optimum proce ssing conditions in terms of excess Si concentration and overall therm al budget are mandatory. The nature of the observed blue emission is d iscussed.
