The photoluminescence (PL) emitted by porous silicon has been investigated under
different conditions of excitation using a pulsed nitrogen laser source, and the
continuous tunable DV synchrotron source at Daresbury Laboratory. The project
involved sample preparation, and PL measurements using a custom-built optical laser-based
system for lifetime measurements. This in itself necessitated software and
hardware development to enable interfacing and data-logging using an IBM-compatible
PC. The equipment development formed a major part of the project. [Continues.]
