II–VI semiconductor nanoparticles synthesized by laser ablation

Laser Group at Liverpool > II–VI semiconductor nanoparticles synthesized by laser ablation

Nanoparticles of the II–VI semiconductors CdTe, CdSe and ZnTe were synthesized by laser ablation (387 nm, 180 fs, 1 kHz, pulse energy of 7 μJ (fluence of 2 J/cm2)) of the target materials in methanol, de-ionized water and acetone. The nanoparticles size distributions follow log-normal functions with median diameters between about 6 and 11 nm for the several materials. The nanoparticles have the same crystalline structure as that of the corresponding bulk material and under the present conditions of ablation are rich in the higher volatility element of the two in the binary alloy and oxidized. Photoluminescence emission in the greenyellow (∼570 nm) was detected from CdSe nanoparticles.
