Show affiliationsNanoparticles of the II–VI semiconductor CdSe were synthesized by laser ablation (387 nm, 180 fs, 1 kHz, pulse energy=4 μJ (fluence=1 J/cm2)) of the target material in methanol. The nanoparticles size distribution follows a log-normal function with statistical median diameter in the range of ≈5–6 nm. Their crystalline structure is the same as that of the bulk material and are Se rich (Cd:Se percentage ratio ~0.8:1). Strong, spectrally "clean" and relatively narrow photoluminescence emission from the produced nanoparticles was detected in the green (~552 nm).
