Significant Enhancement of Circular Polarization in Light Emission through Controlling Helical Pitches of Semiconductor Nanohelices

“…Ceria has special physicochemical properties and will be potentially applied to biochemical catalysis, , biosensing, antioxidation, antibacterial, , and treatment of tumor and ischemia strokes . To the best of our knowledge, however, CPLE has yet been imposed on ceria to seriously limit its bioapplications in a wide range, even though ceria nanostructures have been fabricated to generate photoluminescence in the UV–blue region. − In this work, CdSe and ceria NHs are deposited on supporting substrates by GLAD to emit CPLE. Facile control of substrate rotation during GLAD enables a flexible engineering of helical handedness and P in the nano/micrometer scales, resulting in a control of circular polarization state and a significant increase of the g CPLE values as large as 3 orders of magnitude.…”
