| Abstract: | Er3+ and Yb3+ co-doped Keggin-type polyoxometalates with high luminescence have been synthesized,which has showed much strong near-infrared emission in 1551nm at the room temperature under 980 nm excitation.The Yb3+ ions turn out to be a highly effective sensitive agent to Er3+ ions.The process of energy transfer and emission are discussed in detail. |
