QUANTUM SIZE EFFECT OF SILVER NANOPARTICLE
纳米银粒子的量子尺寸效应

It is prepared two types of silver nanoparticles with different size and discovered the wavelength redshift of the nanoparticle absorption peaks as their size increasing experimently.The dependence of characteristic energy on particle size have been derived by using spherical potential well model and experimental results have been explained by theoritically.
