摘要：
The photoluminescence (PL) properties of the Mn, Pb co-doped ZrO2 nanocrystals have been investigated in detail. A relatively broad and strong emission band centered at about 640 nm was observed originating from the T-4(1) ((4)G) to the (6)A(1), (S-6) transition of Mn-2divided by. In the presence of Pb-2divided by, the luminescent intensities of the ZrO2: Mn nanocrystals have been greatly enhanced due to the energy transfer from Pb-2divided by to Mn-2divided by. As a concentration quenching exists, the optimum value of Pb-2divided by is 5%. (C) 2003 Elsevier B.V. All rights reserved.
