| Popis: | Metal-doped carbon dots (CDs) exhibited promising application in fluorescence and magnetic resonance (MR) imaging, but developing manganese-doped CDs (Mn-CDs) with long wavelength emission and enhanced MR performance is a challenge. Herein, using a one-step solvothermal method, Mn-CDs with redshifted orange emission and enhanced longitudinal relaxation were synthesized for fluorescence and MR imaging. The results indicated that the prepared Mn-CDs had a uniform size distribution, and the average size was 5 nm. Moreover, Mn-CDs possessed a stronger fluorescence performance than Mn-free CDs, and simultaneously, the emission wavelength can redshift from 542 nm (green emission) to 578 nm (orange emission), owing to the increasing N-doping. Because of the movement limit of Mn |
