One is the polymer blend system [.–.] based on the additive color-mixing theory where the blend of the three primary colors (red, green, and blue) or two complementary colors (blue and orang

The significance of this breakthrough is that the long-standing bottleneck problem of triplet energy back transfer from dopants
