中文摘要：

测定了新型含长链β-二酮环状金属铂配合物YDETPt的量子效率、磷光寿命、吸收光谱和发光光谱，并研究了其光致发光和电致发光性能。结果表明，在521nm处有较强的金属配合物三重态磷光发射，是一种绿色磷光材料。配合物在主体材料中掺杂浓度为8％的器件，外量子效率最大，达到0．87％。

英文摘要：

This paper tested the quantum efficiency, phosphorus lifetime, absorption spectra and luminescence spectra of cyclometalated platinum complexes, and its propriety of photoluminescence and electroluminescence. The complex gave rise to a strong photoluminescence at 521nm, and suggests to be a green phosphorescent material. The max external quantum efficiency of OLED （0. 87%） was obtained when doping concentration of complex was 8 percent.
