AI Technical Summary
The rare earth-based phosphors used in existing white LEDs have problems such as limited resources, difficulty in quantitative modulation, uneven spectrum and significant blue light hazard, making it difficult to prepare high-efficiency warm white LEDs.
A three-dimensional coordination polymerization MOF material, [Zn2(OH)(dttd)1.5(tpt)]n, was prepared by solvothermal synthesis using a binuclear-based three-node MOF material as a single-component light-converting agent. This material is then used in warm white LEDs driven by low power.
It achieves the emission of warm white light at low power, has efficient downconversion performance, covers the red, green and cyan wavelengths, reduces blue light hazards, and has excellent energy-saving and environmental protection properties.
