The device studied in this work has the structure of ITO/m-MTDATA:MoOx3:1(8nm)/m-MTDATA(32nm)/ TAPC(10nm)/SFX2PO: Firpic(10nm)/Bphen(40nm)/LiF(1nm)/Al(200nm).
Lee et al[9] and Cheng et al[10] have reported several PO hosts with the structures of DPPO(diphenylphosphine oxide) -bonding carbazole derivatives, in which excellent current- voltage (I-V) characteristics and highly efficient deep-blue electrophosphorescence have been realized.
Normalized EL spectra of A1, A2, A3 and A4 Fig.2. depicted normalized EL spectra of all devices at the driving voltage of 8V.
An emission at 502 nm can be observed in EL of Device A1, which could be attributed to the exceplex emission at the interface of EML/TAPC.
The difference in x is not obvious. y of device A1 is higher than that of devices A2-A4 due to the exceplex emission in its EL.
