A series of white organic electroluminescent devices with a quantum well structure were fabricated based on a new type of organic metal complex bis(2-(4-trifluoromethyl-2-hydroxyphenyl) benzothiazolate) zinc (Zn(4-TfmBTZ)2) by electroplex at NPB/Zn(4-TfmBTZ)2 interface. The results show that the introduction of the hetero-junction quantum well structure can increase effectively the efficiency of electroplex emission, color rendering index(CRI),and the color coordination stability. The optimized device ITO/NPB (60 nm)/Zn(4-TfmBTZ)2(3.0 nm)/NPB (4.0 nm)i> /Zn(4-TfmBTZ)2(30 nm) /Alq3 (30 nm)/LiF(1.5 nm)/Al(150 nm) is obtained with color coordinates of (0.324, 0.337), the highest CRI of 92.5, a maximal brightness of 2013 cd/m2, and a maximal efficiency of 1.03 cd/A,. This device shows very high color stability when the driving voltage is varied from 10 V to 14 V.-
