Description
A Cesium Fluoride doped Organic Light-Emitting Device (OLED) with the structure of ITO/F4- TCNQ:NPB/S-DPVBi/BCP/Alq3/Alq3:CsF/CsF/Al has been fabricated and characterized. This OLED structure has been analyzed and it performance has been compared to a similar non-doped OLED, with the purpose of ascertaining potential benefits. We found that with the small amount of doping wt 0.5%) of CsF into the Alq3 electron transport/emission layer, the electron mobility of the OLED has significantly increased, and thus its optoelectronic properties, such as the I vs. V curve, luminance vs. voltage curve, have shown dramatic increases as well - more than an order of magnitude increase. The spectrum of the CsF doped OLED has shown a single blue peak at around 473 |im, very different from the non-CsF doped OLED, which has shown two convoluted peaks at 450 p.m (deep blue from BPVBi) and at 550 [Lm (green from Alq3).
