Abstract

Development of efficient, inexpensive and environmental-friendly light emitters, particularly devices that produce white light have drawn intense interest due to diverse applications in the lighting industry, photonics, solar energy and others. We present a simple strategy for the fabrication of flexible transparent films exhibiting tunable light emission through one-pot synthesis of polymer matrices with embedded carbon dots assembled in situ. Importantly, different luminescence colors were produced simply by preparing C-dot/polymer films using carbon precursors that yielded C-dots exhibiting distinct fluorescence emission profiles. Furthermore, mixtures of C-dot precursors could also be employed for fabricating films exhibiting different colors. In particular, we successfully produced films emitting white light with attractive properties (i.e., warm white light with a high color rendering index)–a highly sought after goal in optical technologies.
