“…and Si 4+ leads to a considerable shift of the emission maximum to 600nm, allowing the fabrication of a warm-white LED with relatively high color rendering [138,139]. The broadness of the emission spectrum, however, also leads to a considerable fraction of the light being emitted beyond 650nm.…”

Light emitting diodes (LEDs) are on the verge of a breakthrough in general lighting, due to their rapidly improving efficiency. Currently, white LEDs with high color rendering are mainly based on wavelength conversion by one or more phosphor materials. This Review first describes how to quantify the quality of a light source, discussing the color rendering index (CRI) and alternative color quality indices. Then, six main criteria are identified and discussed, which should be fulfilled by a phosphor candidate to be considered for actual application in LEDs. These criteria deal with the shape and position of the emission and the excitation spectra, the thermal quenching behavior, the quantum efficiency, the chemical and thermal stability and finally with the occurrence of saturation effects. Based on these criteria, the most common dopant ions (broad-band emitting Eu AbstractLight emitting diodes (LEDs) are on the verge of a breakthrough in general lighting, due to their rapidly improving efficiency.

“…These utilise the 4f 1 M 5d 1 transitions of Ce 3+ to convert blue light into yellow light, with emission peaking around 550 nm [6,7]. Many other phosphors involving Ce 3+ doping into garnet lattices enable conversion of blue light into the green [8,9] and orange [10][11][12] ranges.…”
