Dual-functional platforms toward field emission displays and novel anti-counterfeiting strategy based on rare-earth activated materials

Rare-earth (RE) ions-activated materials have been widely applied in various applications. In this report, the novel orange-red emitting Sr2YSbO6:Eu3+ phosphors with good photoluminescence and cathodoluminescence were successfully prepared. The obtained sample with good electron penetration depth could be proposed for field emission displays. Besides, a new anti-counterfeiting strategy based on the Sr2YSbO6:Eu3+ phosphorspolydimethylsiloxane (PDMS) film was also provided. Compared to conventional anti-counterfeiting techniques, the phosphors-PDMS film with lots of advantages of eco-friendly feature, stable physicochemical stability, and facile operation is potential for high-level anti-counterfeiting devices, which would be considered to open an avenue to explore novel practical applications.
