| Abstract: | The red-emitting phosphor Sr2YNbO6: x Eu3+ and the orange-red-emitting phosphor Sr2YNbO6: y Sm3+ have been synthesized by the high-temperature solid-state method. All samples were thoroughly tested for phase purity, microscopic morphology, photoluminescence properties, thermal stability, and Commission Internationale de l'Eclairage (CIE) chromaticity coordinates. The results show that there is no impurity phase in the sample, the convergence factors are all less than 10%, the Eu3+ and Sm3+ ions participating in the mixed arrangement are consistent with the target doping concentration, and the microscopic particles are uniform and full. When the concentration of doped Eu3+ and Sm3+ reaches 0.25 mol and 0.02 mol, respectively, the luminous intensity is the best, and it emits red light at 610 nm and orange-red light at 606 nm under excitation at 467 nm and 406 nm, respectively. Dipole-dipole interactions are responsible for the concentration quenching. The quantum efficiencies (QE) are 68.95% and 53.91%, respectively. They all have excellent thermal stability with luminescence intensity at 425 K of 67.3% and 84.8% of room temperature, respectively. Color reproduction (Ra) and comfortable color rendering index (R9). Ra reached 91 and 88, respectively, and R9 reached 73.4 and 65.8, respectively, for the combined white light-emitting diode (WLED) prepared with commercial phosphors and experimental samples. All the results suggest that Sr2YNbO6: RE (Eu3+, Sm3+) can be used as a red phosphor replacements in WLEDs. [ABSTRACT FROM AUTHOR] |
