高显色指数白光LED用新型单组分固态碳点的制备
Preparation of New Single Component Solid Carbon Dots for White LED with High Color Rendering Index
摘要
Abstract
In recent years,the demand for white LED lighting with high color rendering index has posed new chal-lenges to the LED industry.Carbon dots,as a new type of nanomaterial in the 21st century,is expected to become an ideal single component phosphor for white LED devices with high color rendering index,because of its advantages of simple preparation process,high stability,optical tunability and wide emission.However,aggregation-caused quenching (ACQ) of carbon dots greatly limits its application in solid-state lighting.In this paper,high-efficiency fluorescent carbon dots were synthesized by microwave method under mild preparation process with phenphenolline as raw material,and the surface functional group tuning of the carbon dots was realized by doping technique.One-component solid carbon dots phosphors with anti-ACQ were successfully prepared by one-step method,which can be applied to white LED devices with high color rendering index.Its solid quantum yield is as high as 37％,and the white LED prepared with it as phosphor shows excellent photoelectric performance.关键词
