      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.},
