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.
采用三羟甲基丙烷三甲基丙烯酸酯（TMPTMA）的自由基聚合反应，制备了与稀土纳米粒子共混的透明块状聚合物纳米复合材料。这些材料在宽光谱范围的基频（750-850nm）照射下产生连续可调谐的二次谐波（SH）辐射。通过改变纳米粒子中的 Tb(3+)掺杂含量，可以很好地控制 SHG 效率。
