Bright, Stable, and Tunable Solid-State Luminescence of Carbon Nanodot Organogels

Abstract

Despite sustained enthusiastic action with fluorescent carbon nanodots (FCNDs), it still stubbornly remains challenging to achieve bright and widely tunable solid-state luminescence. Herein, organogels embedded with FCNDs are simply synthesized by one-pot pyrolysis method. By excitation of a single ultraviolet (UV) excitation line, tunable solid-state luminescences ranging from blue to red with competitive quantum yields (QYs) (>14%) are subsequently acquired. In this study, N and S elements are co-doped to regulate the aggregation of FCNDs, which consequently modulate the Stokes-shift of the photoluminescence (PL) via managing the degree of photon reabsorption. Notably, without compact aggregations, the dispersions of FCNDs in organogel matrix indeed render competitively high fluorescence quantum yields (QYs), resulting from the suppression of excessive photon reabsorption and nonradiative resonant energy transfer (NRET).
