Steady state heating data (A) for commercial Au nanoshells (black circles), commercial Au nanorods (black triangles) and Cu2−xSe nanocrystals (red squares). Dispersions of nanocrystals (300 μL) were irradiated with 800 nm light at low fluence (2 W/cm2) using a 6 mm spot size. The thermal time constant τout was determined by fitting the temperature fall to Eqn (8). The photothermal transduction efficiency η, was then determined from the steady-state temperature rise using Eqn (9). (B) Plot of the photothermal transduction efficiencies for the Cu2−xSe nanocrystals, Au nanorods (commercial), and Au nanoshells (commercial).
