Co-doping effect of Eu3+ and Sm3+ ions on the red emission from the high-K material SrHfO3

초록

In our search for a new red phosphor, we investigated the photoluminescence from the high-K material SrHfO3 with co-doping of Eu3+ and Sm3+. We found that the red emission from co-doped SrHfO3 depended strongly on the doping concentrations of Eu3+ and Sm3+ and that the intensity was strongest for Eu3+ 1% (x = 0.01) and Sm3+ 1% (y = 0.01) co-doping. We were explain our findings in terms of the energy transfer between the Eu3+ and the Sm3+ ions, and we compared our red phosphor with other commercially-used ones.
