abstract = {Carbon dots (CDs) based fluorescent materials offer
tremendous potential for application in high-definition
displays and advanced illumination systems. However,
achieving solid-state CDs-based phosphors with robust
photothermal stability remains a critical challenge. In this
study, multicolor CDs@ZIF-8 phosphors were synthesized by
precisely controlling the carbonation degree of CDs under
the confinement effect of ZIF-8. Serving as both template
and a protective substrate, ZIF-8 enables the in-situ
carbonation of the carbon source into CDs embedded within
its pores through a solvothermal process. Structural and
compositional analyses following HCl etching of the
multicolor CDs@ZIF-8 phosphors showed that the in-situ
growth of CDs in ZIF-8 pores. The multicolor emission of the
CDs is attributed to the quantum size effect. The rigid
structure of the ZIF-8 backbone imparts exceptional
photothermal stability to the CDs@ZIF-8 phosphors. As a
result, the materials exhibit stable fluorescence under
continuous laser diode (LD) irradiation for up to 60 min and
zero quenching at temperatures as high as 205 °C. These
properties are further validated in LD illumination
applications. This work provides a novel strategy for the
development of high-performance CDs-based phosphors with
excellent photothermal stability and offers significant
insights into the integration of CDs with porous materials.
The findings hold considerable promise for advancing the
design and utilization of CDs in solid-state lighting and
display technologies.},
