Optical generation and detection of the PNBs was performed with a previously developed photothermal laser microscope [44] equipped with a dual pulsed laser (STH - 01, Standa Ltd, Vilnius, Lithuania): each pulse 0.5 ns, the wavelength of 532 nm (matching plasmon resonances of gold spheres of 60 nm) and
tunable near - infrared (matching plasmon resonances of gold nanorods and nanoshells that were employed).
The paper, «Photoluminescent Gold - Copper Nanoparticle Alloys with Composition -
Tunable Near - Infrared Emission,» first appeared online April 3 and later in print April 10 in JACS (Journal of the American Chemical Society).
