Claims18
A formulation for preparing an optical metal oxide layer, wherein the formulation comprises:
- (i) a complex comprising
- a polyoxometalate moiety represented by formula (Ia), and
- a nanoparticle represented by formula (Ib)
- wherein
- each Q independently represents a cation,
- I is any number in the range from 1 to 20;
- n is a number representing the total positive charge n+ of 1 cations Q and the corresponding negative charge n− of the polyanion [XzYpOy];
- X is a heteroatom;
- Y is a metal;
- z is 0 to 20;
- p is 1 to 100;
- and y is 2 to 400;
- M, M′ and M,″ each independently, is a metal;
- i, j, and f each independently, is an integer or a fraction of 0 to 10;
- with the proviso that at least one of i, j, and f is not 0;
- and
- k is any number in the range of from 1 to 20;
- and
- (ii) one or more formulation media.
