摘要：
The photo- and electroluminescence properties of the blend films of Alq(3) and MEH-PPV with various weight ratios are studied. The Forster energy transfer with a relatively large Forster radius (46.9 angstrom) and governs the device luminescent performance, although there are some effect of phase separation. It is found that the energy transfer process governs not only the PL properties in the blend films but also the EL performance of the blend-layer OLEDs. (c) 2008 Elsevier B.V. All rights reserved.
