Superheating water by CW excitation of gold nanodots.

A temperature-dependent photoluminescent thin film of Al(0.94)Ga(0.06)N doped with Er(3+) is used to measure the temperature of lithographically prepared gold nanodots.

Absorption cross section and interfacial thermal conductance from an individual optically excited single-walled carbon nanotube.

The heat generation and dissipation of an individual optically excited metallic single-walled carbon nanotube is characterized using a thermal sensor thin film of Al(0.94)Ga(0.06)N embedded with Er(3+).

Local temperature determination of optically excited nanoparticles and nanodots.

A thin film of Al(0.94)Ga(0.06)N embedded with Er(3+) ions is used as an optical temperature sensor to image the temperature profile around optically excited gold nanostructures of 40 nm gold nanoparticles and lithographically prepared gold nanodots.

Experimental and theoretical studies of light-to-heat conversion and collective heating effects in metal nanoparticle solutions.

We perform a set of experiments on photoheating in a water droplet containing gold nanoparticles (NPs). Using photocalorimetric methods, we determine efficiency of light-to-heat conversion (eta) which turns out to be remarkably close to 1, (0.97 < eta < 1.
