Melt-Quenched Glasses

Tunable Ultralong Phosphorescence

These transparent glasses achieve simultaneous temporal and spectral tuning of ultralong room-temperature phosphorescence through rigid molecular environment and spin-orbit coupling control, and can host dyes for multicolor long-lived luminescence across 520–630 nm.
