Color-tunable white-light-emitting materials based on liquid-filled capsules and thermally responsive dyes

Color-tunable white-light-emitting materials are currently attracting much attention because of their potential applications in artificial lighting, sensing, and imaging. However, preparation of these systems from organic emitters is often cumbersome due to the interchromophoric interactions occurri...
