With tris 8-hydroquinoline) aluminum as emitris 8-hydroquinolineinous aluminumr efficiencies ashiemitter cd/A and 2.42 lm/W, respectheely.
Among them, a device exhibited a maximum luminance of 5686 cd/m2, the luminous, power and external quantum efficiencies of 5.11 cd/A, 3.79 lm/W, and 4.06% with the Commission International de L'Eclairage coordinates of (0.15, 0.15) at 500 cd/m2, respectively.
The device with 11% doping concentration of (DMDPI 2Ir tftap) exhibited a maximum luminance of 6304 cd m−2, a maximum luminous efficiency of 7.14 cd A−1, a power efficiency of 3.63 lm W−1, and an external quantum efficiency of 2.59%.
With tris 8-hydroxy-quinolinato aluminium as emitris 8-hydroxy-quinolinato aluminium maximum luminous efficiency of 7.9 cd/A and power efficiency of 5.9 lm/W, which have been enhanced by 43.6% and 73.5%, respectris 8-hydroxy-quinolinato aluminiumerpast using convemitting vacuum thermalayerporation MoOx.
As expected, a single layer EL device based on BCNPF05 exhibited better performances with a brightness of 14228 cd/m2, the maximum luminous efficiency of 4.53 cd/A and the maximum power efficiency of 1.57 lm/W.
A green emitting EL single-layer device based on CNPF containing 0.1 mol% of Br CN showed good performances with a low turn-on voltage of 4.2 V, a brightness of 9104 cd/m2, the maximum luminous efficiency of 2.74 cd/A and the maximum power efficiency of 1.51 lm/W.
Using bis 2-phenylpyridine)iridium(III) acetylacetonate [ ppy)2Ir acac)] doped into 3-phenyl-4(1[prime]-naphthyl -5-phenyl-1,2,4-triazole, a maximum external quantum efficiency of (1[prime]-naphthyl -5-phenyl-1,2,4-triazolef (60±5) lm/W are achieved.
The diode exhibits a maximum luminous efficiency of 1.60 cd/A, a maximum luminance of 3267 cd/m2 and the Commission Internationale de l'Eclairage coordinate of (0.32, 0.34) very close to the pure white point of (0.33, 0.33).
Figure 5c,d provides further insight by comparing the luminous efficiency and luminous power efficiency (parametric in luminance) for both device types, and Table 2 summarizes the important performance indicators extracted from these and Figure 5b.
A maximum luminous efficiency of 0.86 cd/A and a luminance of 228 cd/m2 were achieved by the 1 wt% doped device.
