- Sub-10 nm In(PO3)3 nanocrystals (NCs) were created in an insulating matrix by rapid thermal
annealing to form nanocomposite structures. On annealing at a temperature of 400 ℃, P2O5
NCs were formed by substituting P for Zn atoms in ZnO films via the kickout diffusion
mechanism based on the fixed oxygen sublattice. On annealing at a higher temperature of
600 ℃, however, In(PO3)3 NCs were nucleated by diffusion of In atoms from the substrate into
the sites of P2O5 NCs that coalesced by moving atoms to neighboring grains in the strain
relaxed region. The formation mechanisms of sub-10 nm In(PO3)3 NCs in an insulating matrix
due to rapid thermal annealing are described on the basis of the experimental results.
