Abstract

Bright two-photon luminescence of gold and silver nanoparticles photodeposited in titanium dioxide matrix was studied under near IR laser pulse irradiation. Electromagnetic field enhancement coefficients were estimated for the most intense hot spots at wavelength of excitation. The estimation was compared with theoretical predictions of FDTD analysis.
