英文摘要Eu2+-doped zns nanoparticles with an average size of around 3 nm were prepared, and an emission band around 530 nm was observed. by heating in air at 150 degrees c, this emission decreased, while the typical sharp line emission of eu3+ increased. this suggests that the emission around 530 nm is from intraion transition of eu2+: in bulk zns:eu2+, no intraion transition of eu2+ was observed because the excited states of eu2+ are degenerate with the continuum of the zns conduction band. we show that the band gap in zns:eu2+ nanoparticles opens up due to quantum confinement, such that the conduction band of zns is higher than the first excited state of eu2+, thus enabling the intraion transition of eu2+ to occur.
