1：Experimental Design and Method Selection:

The study involved synthesizing Zr-MOFs and carbon dots, then compositing them using AEATMS as a binding agent to create a white light-emitting material. The rationale was to leverage the properties of MOFs and CDs for efficient, stable emission without rare-earth elements.

2：Sample Selection and Data Sources:

Zr-MOF was synthesized from H4L ligand, ZrOCl2·8H2O, and benzoic acid in DMF. CDs were synthesized from citric acid and urea in ammonia water. Commercial UV LED chips were used for device fabrication.

3：List of Experimental Equipment and Materials:

Materials included citric acid, AEATMS, ethyl acetate, hexane, DMF, acetone, methanol, CH3CN, urea, and water. Equipment included a microwave oven, centrifuge, fluorescence spectrometer (FLS920P), quantum efficiency system (FP-6000 Series), TEM (Philips CM 20 FEG), XRD diffractometer (Bruker AXS D8 Quest CMOS), photometer (Spectrascan PR650), power source (Keithley 237), and TGA equipment (PerkinElmer STA 6000).
