Disclosed is a green phosphor which can enhance internal quantum efficiency.
Provided is a yellow fluorescent body that has increased internal quantum efficiency.
The ceramic body may, in some embodiments, exhibit superior internal quantum efficiency (IQE).
The textured layers enhance light extraction, and the use of nonpolar orientation greatly enhances internal quantum efficiency compared to conventional devices.
Provided is a nitride semiconductor light emitting element which has improved internal quantum efficiency of a light emitting layer and has high output.
The internal quantum yield may thus be increased above 1.
The individual diodes are characterised by a high internal quantum yield, but can be optically thin (peak absorption < 80%).
Therefore, the internal quantum yield is increased, the light emitting efficiency is increased, and a drive voltage can be lowered.
The metallic nanoparticles improve the internal quantum efficiency of the luminescent material, thus enabling the lutecium oxide luminescent material to have a relatively high luminous intensity.
Described herein are batches of nanoscale phosphor particles having an average particle size of less than about 200 nm and an average internal quantum efficiency of at least 40%.
