Facile Synthesis of Water-Stable Multicolor Carbonized Polymer Dots from a Single Unconjugated Glucose for Engineering White Light-Emitting Diodes with a High Color Rendering Index
Semiconductor polymer dots were encapsulated into a SiO2matrix to form highly fluorescent nanocomposites. The photostability and thermal stability of nanocomposites were greatly improved, making them promising candidates for white-light emitting devices with a high color-rendering index.
WLEDs were fabricated with commendable color rendering index, widely variable color temperatures and high luminous efficacy by combining green and red emitting polymer dots on YAG:Ce-based WLEDs.
