Doped semiconductor powder and preparation thereof |
摘要 |
The invention provides a doped semiconductor powder comprising nanocrystals of a group IV semiconductor and a rare earth element, the rare earth element being dispersed on the surface of the group IV semiconductor nanocrystals. The invention also provides processes for the preparation of the above doped semiconductor powder, and a composite material comprising a matrix in which is dispersed a doped semiconductor powder.
