摘要
The high-temperature solid-phase method synthesized a series of red phosphors Ca2InTaO6: xEu3+. Their most substantial emission peak is at 612 nm, FWHM = 8 nm, and they can be excited under blue light. Has very excellent thermal stability, still has 77.7% of normal emission intensity at 150 °C, and the luminous intensity decreases very slowly between 80 °C–150 °C. In the high temperature durability test at 120 °C and 150 °C, the sample can still maintain good luminous intensity for a long time. The WLED was fabricated using fabricated samples in combination with commercial green and blue phosphors; it has Ra = 90.1 and R9 = 83.4. All expected test results prove that this sample is suitable for modern LED lighting.
