A transparent and electrical conductive layer comprising LiF and Al was designed and obtained successfully.The composite layer was characterized using transparency spectroscopy and sheet resistance measurement.As shown in Table 1,when the ratio of LiF∶Al reached 4∶4,the sheet resistance and transmittance of the composite layer were measured to be 573 Ω/(□) and 55.5％ (at 532nm),respectively.Transparent organic light-emitting diodes (TOLEDs) employing LiF∶Al composite layer as cathodes were fabricated and the electroluminescent properties of the TOLEDs were investigated.
