However, a significant challenge in practical applications has emerged concerning the development of solid-state fluorescence (SSF) materials. This study addresses this knowledge gap by exploring the unexplored photonic facets of C-based solid-state microphotonic emitters. The proposed synthesis approach focuses on carbonized polymer microspheres (CPMs) instead of conventional nanodots. These microspheres exhibit remarkable SSF spanning the entire visible spectrum from blue to red. The highly spherical shape of CPMs imparts built-in photonic properties in addition to its intrinsic CD-based attributes. Leveraging their excitation-dependent photoluminescence property, these microspheres exhibit amplified spontaneous emission, assisted by the whispering gallery mode resonance across the visible spectral region. Remarkably, unlike conventional semiconductor quantum dots or dye-doped microresonators, this single microstructure showcases adaptable resonant emission without structural/chemical modifications. This distinctive attribute enables a plethora of applications, including microcavity-assisted energy transfer for white light emission, highly sensitive chemical sensing, and secure encrypted anticounterfeiting measures. This interdisciplinary approach, integrating photonics and chemistry, provides a robust solution for light-element-based SSF with inherent photonic functionality and wide-ranging applications. description_type: abstract lang: und ## Creator - name: Barun Kumar Barman role: author orcid: https://orcid.org/0000-0002-9894-1890 organization: National Institute for Materials Science ror: https://ror.org/026v1ze26 - name: David Hernández-Pinilla role: author - name: Thang Duy Dao role: author - name: Kenzo Deguchi role: author organization: National Institute for Materials Science ror: https://ror.org/026v1ze26 - name: Shinobu Ohki role: author orcid: https://orcid.org/0000-0002-7357-3833 organization: National Institute for Materials Science ror: https://ror.org/026v1ze26 - name: Kenjiro Hashi role: author orcid: https://orcid.org/0000-0002-0320-4768 organization: National Institute for Materials Science ror: https://ror.org/026v1ze26 - name: Atsushi Goto role: author orcid: https://orcid.org/0000-0002-9472-4098 organization: National Institute for Materials Science ror: https://ror.org/026v1ze26 - name: Tsuyoshi Miyazaki role: author orcid: https://orcid.org/0000-0003-3534-4404 organization: National Institute for Materials Science ror: https://ror.org/026v1ze26 - name: Karuna Kar Nanda role: author orcid: https://orcid.org/0000-0001-9496-1408 - name: Tadaaki Nagao role: author orcid: https://orcid.org/0000-0002-6746-2686 organization: National Institute for Materials Science ror: https://ror.org/026v1ze26 ## Contact agent ## Publisher organization: American Chemical Society (ACS) ## Managing organization ## Keyword - subject: carbon dots schema: not_defined - subject: carbonized polymer microsphere schema: not_defined - subject: energy transfer schema: not_defined - subject: white-light emission schema: not_defined - subject: anti-counterfeiting schema: not_defined ## Rights - description: This document is the Accepted Manuscript version of a Published Work that appeared in final form in Bioinspired Carbonized Polymer Microspheres for Full-Color Whispering Gallery Mode Emission for White Light Emission, Unclonable Anticounterfeiting, and Chemical Sensing Applications, copyright © 2024 American Chemical Society after peer review and technical editing by the publisher.
