Abstract:

In present work, K₂Y_1-xZr (PO₄)₃:Pr_x³⁺ (0.01x0.05) samples were prepared by solid-state reaction method and their photoluminescence properties were investigated in ultra-violet (UV) and vacuum ultra-violet (VUV) region. The photon cascade luminescence (PCL) of Pr³⁺ had been observed. All the results indicate that, in this Pr³⁺-doped K₂YZr (PO₄)₃ phosphor, even if the ¹S₀ state is higher than the lowest 4f5d energy level, the photon cascade emission (PCE) process for Pr³⁺ still could occur under 147 nm and 234 nm (4f¹5d¹ state) excitation. Therefore, K₂YZr (PO₄)₃ was an ideal host for Pr³⁺ to implement the PCE process successfully.
