4. Conclusions
Cadmium selenide nanoparticles were successfully synthesized
in CTAB microemulsions under ambient conditions like room
temperature and non-inert atmosphere. These nanoparticles were
found to exhibit strong room temperature photoluminescence
with two emission peaks at 500 and 580 nm. The photo-excitation
above exciton absorption peak position gives only the band gap
photoluminescence with the peak position at 500 nm whereas, the
photo-excitation below exciton absorption peak position gives
