A method of predicting photostability of coatings with various dopants on titanium dioxide pigment particles is disclosed. Calculations of the density of states show that a doped coating which reduces the density of states near the band edge or increases the density of states within the band gap of the...http://www.google.com/patents/US7763110?utm_source=gb-gplus-sharePatent US7763110 - Titanium dioxide pigment particles with doped, dense SiO2 skin and methods for their manufacture
