A New Transparent Organic Glass with Unity Photoluminescence Quantum Yield

) of 178 °C, and a thermal decomposition temperature of 270 °C. Apart from the blue-emitting glass, green- and red-emitting glasses of high transparency were synthesized varied chromophores, including 9,10-bis(phenylethynyl)anthracene (BPEA) and rhodamine B. In a proof-of-concept experiment, these glasses were used to encapsulate UV LEDs via a simple dipping process, which showed a satisfactory color rendering ability. This work brought a new member into the family of transparent luminescent glasses, promising many applications in areas including full-color displays and large-area mini-LED panels.
