“…As for other films with PBG at 589, 688, and 759 nm, the 520 and 539 nm emissions were enhanced, while 654 nm emission intensity decreases due to the PBG effect, leading to the increase of value of I 520 /I 654 and I 539 /I 654 . [ 143 ]…”

The responsive control of energy transfer (ET) plays a key role in the broad applications of lanthanide‐doped nanomaterials. Photonic crystals (PCs) are excellent materials for ET regulation. Among the numerous materials that can be used to fabricate PCs, chiral nematic liquid crystals are highly attractive due to their good photoelectric responsiveness and biocompatibility. Here, the mechanisms of ET and the photonic effect of chiral nematic structures on ET are introduced; the regulation methods of chiral nematic structures and the resulting changes in ET of lanthanide‐doped nanomaterials are highlighted; and the challenges and promising opportunities for ET in chiral nematic structures are discussed.
