Garnet-type phosphor -- Near infrared -- Phosphorescence emission -- Thermoluminescence
Аннотация: Garnet-type Y3Sc2Ga3O12:Cr3+ phosphor has been synthesized by a solid-state reaction. XRD result revealed the successful phase formation and Cr3+ doping in Y3Sc2Ga3O12. The excitation spectrum at about 260, 450, and 630 nm corresponded to three spin-allowed Cr3+ d-d intra-transitions of 4A2-4T1 (4P), 4A2-4T1 (4F), and 4A2-4T2 (4F), respectively, among which the near infrared (NIR) emission peak at around 740 nm is identified. Moreover, the phosphorescence emission property, thermoluminescence and related luminescence mechanisms are discussed as well. The fabricated NIR phosphor-converted light-emitting diodes (pc-LEDs) suggest its potential of Y3Sc2Ga3O12:Cr3+ phosphor for non-visible light source application.
