| 摘 要： | 采用柠檬酸钠还原法制备了不同粒径的金粒子，并研究了金粒子的共振散射光谱。结果表明，金粒子在粒径１０～９５ｎｍ范围内呈红色，最大吸收波长在５１７．８～５５３．３ｎｍ范围内。随着金粒子粒径增大，吸收峰红移。粒径为１０～９５ｎｍ金粒子的最强共振散射峰位于５８０ｎｍ处，此波长处的共振散射光强度３Ｉ与金粒子粒径ｄ成正比。

| Abstract: | Au particle of the size in the range of 10－189 nm has been prepared by sodium citrateprocedure. The resonance scattering spectra of Au particle have been studied. The nanoparticle solutions ofthe size in the range of 10－95 nm exhibit red in colour. Their maxmum absorption wavelenth are in therange of 517.8－533. 3 nm. The absorption peak shifts to the red with the size increasing. The maxmumresonance scattering peak is at 580 nm. The cube root of the intensity at 580 nm is proportional to the sizeof Au particles. |
