The experiment results show that the prepared YPO4 : Tb is about 40 nm. As a result the method of copricipation is a better way to prepare Nanostructured particles. The luminescence spectra of nanosized YPO4: Tb shows that it emits bright green.是什么意思_The experiment results show that the prepared YPO4 : Tb is about 40 nm.
