“…As a result, the PL intensity is concentrated mainly on the magnetic dipole 5 D 0 → 7 F 1 transition (590 nm) instead of the electric dipole 5 D 0 → 7 F 2 transition (606 and 628 nm) [5]. Many studies on the PL characteristics of YAG:Eu crystalline powders reported that the 5 D 0 → 7 F 1 transition showed higher intensity than the 5 D 0 → 7 F 2 transition [4][5][6][7][8]. On the other hand, the emission intensity of the YAG:Eu glass-ceramic was concentrated at the 5 D 0 → 7 F 2 transition because Eu 3+ in the YAG glass-ceramic is located at sites with low symmetry.…”

The forced electron dipole Overall, YAG:Eu glass-ceramic can be used as a phosphor with orange-red emission, which is potentially suitable for contrast-enhanced PDP applications [8].…”

“…Tuy nhiên, hiệu suất phát quang của đèn huỳnh quang có thể tăng mạnh nếu cường độ huỳnh quang của bột đỏ chuyển dịch về phía bước sóng ngắn hơn với sự giảm hệ số trả màu trong vùng cho phép. Nếu đỉnh phát xạ của bột đỏ dịch chuyển từ 611 nm về 595 nm trong khi giữ nguyên đỉnh phát xạ của bột xanh lục và xanh lam thì hệ số trả màu có thể rơi xuống khoảng 60 -65 nhưng hiệu suất phát quang lại tăng thêm 12% [2]. Điều này đã mở ra một xu thế mới rằng có thể thay thế bột Y 2 O 3 : Eu bằng một loại bột huỳnh quang khác với ion pha tạp Eu 3+ trên mạng nền.…”
