Specifications

Emission Peak

{'zh': '620', 'en': '620'} nm

Advantages

Visible-light-excitable

Emission intensity under 468 nm excitation matches commercial SrAl2O4:Eu2+,Dy3+ under UV, eliminating the need for UV light sources.

Multi-stimuli-responsive

Besides photoluminescence, it exhibits red persistent luminescence and tunable photo-/thermo-/mechano-stimulated luminescence for multifunctional devices.

High red emission intensity

Under 468 nm excitation, the red emission at 620 nm matches the intensity of commercial SrAl2O4:Eu2+,Dy3+ under UV irradiation.

Applications

• White LED：Visible-light-excitable red emission replaces UV-excited red phosphors in white LEDs
• Display Devices：Multi-modal luminescence can be integrated into displays for multifunctional purposes
• Optical Anti-counterfeiting：Multi-stimuli-responsive luminescence enables encrypted anti-counterfeiting labels
• Information Storage：Persistent and tunable stimulated luminescence can be used for information storage and retrieval
