Abstract

HgTe and HgTe/CdTe core-shell structured nanoparticles were synthesized by the colloidal method. The photoluminescence (PL) spectrum of a HgTe/CdTe nanoparticle film exhibited an exciton peak at 700 nm, which was blue-shifted by about 400 nm for the HgTe nanoparticle film. The current-voltage curves and photoresponse of the HgTe/CdTe nanoparticle film were compared with those of the HgTe nanoparticle film. When the film is exposed to light, the current of the HgTe/CdTe nanoparticle film decreases in the ambient air while increasing in vacuum. Finally, the temperature dependence of the photocurrent is discussed in this paper.
