“…Analyzing the luminescence spectra of Fig. 4, it can be noticed that the pure SbPO glass, SbPO3Cr, and SbPO6Cr presented typical Sb 3+ spectra dominated by bands in the blue region of the visible spectrum [34]. The Sb 3+ is an s 2 ion which emits in the blue Table 2 Energy levels splitting for d 3 ions from Tanabe-Sugano diagram, and electronic transitions observed in absorption spectra of SbPO:Cr 3+ glasses.…”

“…The first way is less suited when using near-UV or blue pumping LEDs. Sensitizing can be achieved by codoping with Eu 2+ [116,117], Ce 3+ [118] or Sb 3+ [113,119]. The energy transfer from the sensitizer to the Mn 2+ centers occurs via exchange interaction, requiring a first neighboring position [63].…”

“…A ,Mn 2+ as a well-known white-light emitting lamp phosphor [113,119]. Most ns 2 -based phosphors lack efficient excitation bands in the blue or near-UV part of the spectrum, which probably explains why they are hardly investigated as LED phosphor.…”

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.

“…The increase of the halfwidth points to a vibrational frequency involved of some 120 cm-r, which seems to be reasonable. A shift to higher energy has been observed before for s2 ions with large Stoke shifts (20,21).…”
