Where can I get absorption coefficient of anatase TiO2 for 633nm light at standard ambient temperature and pressure?

I'm using dynamic light scattering to measure size of TiO2 nano-particle, and I need the absorption of TiO2. I looked up many literature, but I only found a spectrum of the absorption, no accurate...

How to make a dispersion of TiO2 nanoparticles for spin-coating on polymer film without severe agglomeration?

I was trying sonicating the TiO2 in isopropanol for several hours. But the size was still more than 100nm. After the coating the size was even bigger, up to micron meters. Anyone have suggestions?
