title: Controlled synthesis of bulk polymer nanocomposites with tunable second order nonlinear optical properties.
abstract: The transparent bulk polymer nanocomposites blended with rare earth nanoparticles are prepared through the radical polymerization of trimethylolpropane trimethylacrylate (TMPTMA). These materials produce continuously tunable second harmonic (SH) radiation under illumination of a wide spectral range of fundamental waves (750-850 nm). The SHG efficiency can be controlled well by altering the Tb(3+)  doping content in the nanoparticles.
