Abstract

Materials with circularly polarized luminescence have recently gained increasing interest due to their potential applications in three-dimensional displays, optoelectronic devices, optical sensors, and optical information storage.1,2 Emitters with circular polarization in the near infrared (NIR) part of the spectrum have been found to have advantages over visible light for the areas of bioimaging and telecommunications. This is due to low absorption of NIR light in biological samples, which allows for high-quality imaging and minimal sample damage, and low attenuation of NIR light in optical fibers, which is ideal for long-distance communication.3,4,5 Only a few NIR active chiral emitters have been reported and characterization equipment for circularly polarized light detection in the NIR is limited; this has made the development of materials with optical activity in this optical range challenging. This work seeks to expand this material library through simple compositional tuning of established chiral semiconductor morphologies that exhibit strong circularly polarized light emission in the visible region.
