金纳米双锥的光热特性研究
Study on the Photothermal of Au Nano Bipyramids
摘要: 本文采用种子介导法制备了金纳米双锥光热剂，评价了其光热转换性能。制备出的金纳米双锥吸收峰位于808 nm。在2 W/cm2的808 nm激光辐照下，温度升高值为33.3℃，且连续升降温循环5次升降温幅度基本无变化。光热转换效率为44.28%。具有优异的光热性能和光热稳定性。
Abstract: In this paper, gold nanoscale double-cone photothermal agent was prepared by seed-mediated method and its photothermal conversion performance was evaluated. The absorption peak of the prepared gold nano double-cone diagnostic agent was 808 nm. Under the irradiation of 808 nm laser of 2 W/cm2, the temperature rise value is 33.3˚C, and the temperature rise amplitude of 5 consecutive irradiation is basically unchanged. The photothermal conversion efficiency is 44.28%. It has excellent photothermal properties and photothermal stability.
