GdAl3(BO3)4:Cr3+ is used to fabricate a NIR-pc-LED that shows promise for plant lighting and applications in the nondestructive analysis of agricultural products.
The near-infrared light-emitting diodes using PbSe quantum dots were fabricated with the highest external quantum efficiency of 2.52%, which is comparable to those commercial InGaAsP LEDs and visible quantum dot electroluminescence LEDs.
