Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
A series of blue-emitting poly(2,8-indenofluorene-co-2,7-carbazole)s, namely P(IF-Cz10), P(IF-Cz25), and P(IF-Cz50), has been designed and synthesized for use in polymer light-emitting diodes (PLEDs). With increasing carbazole content, the resultant copolymers are found to show blue-shifted emission and reduced photoluminescence quantum yields (PLQYs) in films. Consequently, P(IF-Cz25) represents the best trade-off between PLQY and blue light of these materials. The corresponding device reveals a peak external quantum efficiency of 4.12% (3.19 cd A-1, 2.78 lm W-1) and Commission Internationale de L'Eclairage coordinates of (0.150, 0.081). The results clearly indicate that the copolymerization of indenofluorene and carbazole is a promising strategy for developing blue PLEDs with simultaneous high efficiency and good color purity, with a CIEy value of <0.10.
