IntroductionClick to copy section linkSection link copied!Lanthanide-doped nanoparticles (LnNPs) possess unique optical properties and their usage has been demonstrated in a wide range of optoelectronic applications, including upconversion, (1−3) imaging, (4−6) photocatalysis, (7,8) and lasing. (9−11) One of the key limitations of LnNPs is their low absorption cross-section, with molar absorption coefficients of lanthanide ions rarely exceeding 1 M–1 cm–1.

AbstractPolarized light is critical for a wide range of applications, but is usually generated by filtering unpolarized light, which leads to substantial energy losses and requires additional optics. Here we demonstrate the direct emission of linearly polarized light from light-emitting diodes made of CsPbI3 perovskite nanoplatelet superlattices.
