Broadband near-infrared (NIR) emission realized by the crystal-field engineering of Y3-xCaxAl5-xSixO12:Cr3+ (x= 0-2.0) garnet phosphors

The rapid development of portable spectrometers has evoked a large demand for minimized light sources; meanwhile, NIR phosphor-converted light-emitting diodes (NIR pc-LEDs) are an optimal choice due to their compactness and low cost. The phosphors used in NIR spectroscopy (NIRS) are required to have...
