The turn-on voltage of P-mPCCP and T-mPCCP composing device was 4.0 and 7.0 eV and showed a maximum luminance of 21,100 and 3290 cd/m2 and a maximum luminance efficiency of 15.0 and 7.6 cd/A, respectively.
Among these devices, the device based on hydrogen-terminated compound (12) displays the best performance with a high maximum luminance of 670 cd/m2, a low turn-on voltage of 4.20 V, and a maximum luminance efficiency of 0.38 cd/A.
A triple-layer device based on this blend exhibited higher maximum brightness and luminance efficiencies relative to those of the pure polyfluorene.
High luminance efficiencies of 2.3 cd A−1 were achieved for single-layer device; luminescence efficiencies of 4.4 cd A−1 were achieved for a double-layer device.
Small molecular materials are described with emphasis on their material issues pertaining to charge transport, color, and luminance efficiencies.
The response times of a Dell 3007 WFP monitor have been measured for luminance transitions between 0% and 100% of the maximal luminance of the monitor in five steps.
It allows a panoramic stimulation that covers large parts of the visual field of flies and is equipped with ultra-bright LEDs (maximal luminance ca. 12,000 cd/m).
The best performance was obtained with P4 device, in which the maximum luminance and luminance efficiency were 11 501 cd/m2 and 10.6 cd/A, respectively.
The performance of MEH-PPV device (maximum luminance: 9310 cd/m2, luminance efficiency: 0.26 cd/A) was effectively enhanced by inserting the thermally cross-linked HTP or HTPOCH3 as HTL (HTP: 12610 cd/m2, 0.32 cd/A; HTPOCH3: 140.33cd/A2, 0.33 cd/A).
Compared with other devices, the RGO LB film device achieves excellent performance in driving voltage, maximum luminance, and luminance efficiency.
