Hence, the lattices act like lenses, diverting more of the photons out of the chip, thereby improving the external efficiency.
But while internal efficiency helps me keep my costs down and stay on top of things, it's my external efficiency that keeps clients coming back.
Here, we review the synthesis, properties, and device performances of DP-PPV derivatives, which exhibit high external efficiency and brightness in polymer light-emitting diodes.
External efficiency relates to the extent of government concerned about the needs of individuals.
Based on the 2010 Chinese general social survey data, this research will explore political efficiency (internal efficiency and external efficiency) and the impact of three forms of political participation (rightful resistance, social participation, and grassroots election) on police trust.
Rice genotypes show significant variability for N uptake (external efficiency) and N utilization (internal efficiency) with yield being predominantly determined by the uptake process, particularly under low-N conditions (Singh et al. 1998; Witcombe et al. 2008).
Device performance characteristics such as luminance, current efficiency, photoluminescence efficiency, and external quantum efficiency are tabulated.
The maximum power efficiency, current efficiency and external quantum efficiency for the complex based OLED are up to 48.46 lm/W, 55.04 cd/A and 18.47%, respectively.
It exhibited high current efficiency and external quantum efficiency of 4.96 cd A−1 and 4.20%, respectively.
The average reflectivity, internal quantum efficiency (IQE), and external quantum efficiency (EQE) are shown in Fig. 6.
