Influence of Indium-tin Oxide Reutilization on The Performance of Organic Light-emitting Devices
NaOH solution and HCl solution were used to recycle the used indium-tin oxide (ITO) substrate. The treated surface was then observed by using atomic force microscopy (AFM)
while organic light-emitting devices (OLEDs) were fabricated with the recycled ITO to study the influence of reutilization on the performance of OLED. The results show that such treatments can efficiently remove the residual aluminum electrodes on the used ITO and change the chemical composition of the surface
especially by the NaOH treatment. OLED based on such recycled ITO can achieve a current efficiency of 12.08% with an increase of 14.7% compared with that based on new ITO
while the external quantum efficiency reached 5.23% with an increase of 11.7%. In addition
the sterically hindered between the chromophores and between chromophore and auxochrome increased
resulting in the enhanced side-band effect in the electroluminescence spectrum of the device when ITO was processed by different methods.
