Green photonics aims to provide solutions that generate or save energy, reduce pollution and greenhouse gas emissions,
produce environmentally sustainable outputs or enhance public health. Solid-state lighting (SSL), one of the most important
green photonics technologies, offers 50% reduction in global electricity consumption for lighting that corresponds to the
production by hundreds of coal plants and decrease in millions of tons of carbon emission, if the entire conventional white
light sources are to be replaced with energy-efficient light emitting diodes (LEDs). However, the widely used phosphorbased white LED technology and the currently investigated nanocrystal-based white LEDs have limitations in terms of
biocompatibility, energy efficiency and color quality. To this end, we propose a new class of color-conversion LEDs
integrated with proteins to overcome the disadvantages of currently used and investigated color conversion materials. For
this, we will work on the theoretical modeling, design, fabrication and experimental realization of these new solid-state
lighting devices. The excellent optical properties of the fluorescent proteins including strong absorption, high fluorescence
quantum yields and high photostability will enable us to achieve efficient and stable white light generation. Furthermore, the
biocompatible characteristics of the proteins have the potential to minimize the pollution caused by the color-conversion
materials and make them a strong candidate for “green lighting”. These hybrid photonic devices will embody fluorescent
and transparent silk-fibroin proteins on III-V InGaN/GaN light-emitting structures. This project aims for protein-integrated
color-conversion white LEDs that are expected to simultaneously achieve high-quality, efficient and eco-friendly solid-state
lighting. Therefore, this project offers a potential solution to help addressing economical and environmental challenges we
are now facing due to the energy problem.
