High-Brightness Green-Light Emitting Thin-Film Electroluminescent Device

Using the second o-nitro aniline and benzoyl chloride as the initial raw materials, a green light-emitting materials (pbi)2Ir (acac)2 was produced utilizing a new designed synthesis plan. The complex’s structures were characterized by IR, MS, and the differential thermal analysis. The optical Luminescence Properties of the complex was studied by the fluorescence spectrometry analysis. The melt point of the product is 343°C which showed that it had thermal stability.. The fluorescence spectrometry analysis experimental results show that the Excitation and emission peaks of the organic Iridium (Ⅲ) complexes got were respectively 470.6nm and 526.21nm which showed that it belong to green high-brightness light-emitting materials. The oxidation of the intermediate products exposed in air which could cause the quality of product instability was avoided in the new synthesis plan improved.

Better Than

We studied the influence on the organic electroluminescent device performance with different DPAVBi position. When DPAVBi was the separate blue light emitting layer and its thickness was 20 nm, the performance of the device is better than others. The yellow light device performance with DPAVBi behind the Rubrene layer is better than the device with it in front of Rubrene layer. The device has a maximum luminous 23560 cd/m2 at 17V and maximum efficiency 6.63cd/A at 16 V. We have received the blue-green light device with the Rubrene doped to DPAVBi. The maximum efficiency is 5.37 cd/A at 9 v and the maximum luminance is 6377 cd/m2 at 16 V. The efficiency drops slowly when the voltage increases. So, all the devices have the current weak fluorescence quenching.
