Abstract
Covid-19 pandemic has escalated the use of plastic waste across the globe that takes hundreds of years to de- grade and finally end up as micro plastics in soil. In this work we report recycling of one time use plastic waste bottles to white light emitting carbon dots (CDs) using a pyrolytic method. Plastic waste takes hundreds of years for natural degradation and is a major cause of environmental pollution. We address this issue by recycling plastic waste bottles to CDs. Further the fabricated CDs are characterized using UV-absorption emission spectroscopies. Using our unique recycling technique, broadband single system white light emitting CDs with broad absorption and emission bandwidth of ~ 135 nm are synthesized. These dots have potential to replace semiconductor quantum dots as active emitters in next generation artificial lighting devices.
