电致发光电槽中染料电化学行为的研究
Study of Behaviors of Organic Dyes in Electroluminescence Cell
【摘要】 用电化学循环伏安法和紫外光谱法 ,比较了Alq和PBD的紫外吸收谱图及I V曲线上的电化学行为。实验结果指出 ,Alq和PBD的电化学行为均不可逆 ,均有大的阴极还原峰电流 ,表明它们可用作为优良的电子传输体。从氧化还原峰的分析所得到的带隙宽度的定性结果与UV图上的结果相一致
【Abstract】 Ultra violet spectrograph and voltammograms of luminescence organic material, Alq and PBD are investigated.Results of I V cyclic voltammograms indicate that the electrochemistry of Alq and PBD is unreversible with a big cathodic current peak, and that the cathodic reduction potential of PBD is more negative than that of Alq.Results of UV and voltammograms are both in a good agreement with the electroluminescence behaviors.
