Ultrafast luminescence of Ga- and In-doped ZnO ceramics

In the presented work we compare luminescence characteristics of ZnO:Ga and ZnO:In ceramics prepared by hot uniaxial pressing method. Two types of initial powders were used. The first one was nanosized powder prepared by precipitation method. In the second case we used microsized powders and mechani...
