Ultrastable red-emitting phosphor-in-glass for superior high-power artificial plant growth LEDs
Ultrastable red-emitting phosphor-in-glass (PiG) consisting of 3.5MgO·0.5MgF 2 ·GeO 2 :Mn 4+ (MMG:Mn 4+ ) phosphor in a glass matrix was prepared for superior artificial plant growth LEDs (PGLs).

Further analysis also demonstrated that promotive effect can also be obtained in the level of ascorbic acid, soluble protein, soluble sugar and total chlorophyll. The PiG strategy presented in this paper afforded superior high-power artificial plant growth LEDs, which are crucial in the application of ecological agriculture.
Red-emitting phosphor-in-glass with excellent thermal stability was prepared, showing great potential for high-power LED plant-growth lamps with high color stability. |
