Spectral Variations of Eu~(2+) Emission in Sr- or Ba-Silicate, Borate and Borosilicate Hosts

摘要

Depending on host environments, Eu~(2+) emission can be spectrally tuned by manipulating the energy levels between allowed 4f?5d transition. Spectral variations of Eu~(2+) emission from narrow green emission to broad yellow emission band were achieved by varying the host lattices such as Sr- or Ba-silicate, borate, and borosilicate.
