[求助] 有散射的纳米粒子,如何测量量子产率?

小弟新手,刚接触这行。。。。现在又一种无机材料,100nm左右。。。用相对法测量子产率,发现散射太高,结果不可靠。。。请问各位大神,这种情况应该怎么办?越详细越好,谢谢!

My suggestions:
(1) Try to use low particle concentration to minimize the effect of scattering.
(2) Correct the absorbance by using suitable control sample. For example, if possible, measure the scattering level of similar sized polymer particles (e.g., polystyrene particles) at the same concentration.

Welcome other ideas!
