Probing The Origin Of Second Harmonic Generation From Copper Nanoparticles In Solution By Hyper-Rayleigh Scattering
In recent years, coinage metal nanoparticles have emerged as materials with largest quadratic optical nonlinearity. Their first hyperpolarizabilities (β) are very high (105-106 x 10-30 esu) but such large values were quite unexpected because of their apparently centrosymmetric bulk structure. Only a...
