Plastic waste was transformed into high-performance quantum dots (QDs), combining technological innovation with a focus on environmental sustainability. The excellent fluorescence properties of the synthesized quantum dots were utilized to detect Fe and F ions with high sensitivity and selectivity in an "on-off-on" dual-mode fashion. Additionally, the synthesized quantum dots exhibited stable solid-state fluorescence, enabling their use in solid-phase applications without the typical fluorescence loss observed in other materials. The versatility and tunability of the synthesized materials were demonstrated by producing three different emission colors, achieved through the incorporation of various heteroatoms during the synthesis process. This solid-state fluorescent material provides a pathway for sensing and optoelectronic applications, as well as advanced optical devices with customizable designs in the future.
塑料垃圾被转化为高性能量子点（QDs），将技术创新与对环境可持续性的关注结合在一起。合成的量子点具有优异的荧光特性，可用于以“开-关-开”双模式高灵敏度和高选择性地检测铁离子和氟离子。此外，合成的量子点表现出稳定的固态荧光，使其能够用于固相应用，而不会出现其他材料中常见的荧光损失。通过在合成过程中引入各种杂原子，制备出三种不同发射颜色的材料，证明了合成材料的多功能性和可调性。这种固态荧光材料为传感和光电子应用以及未来具有可定制设计的先进光学器件提供了一条途径。
