The improvement of the color rendering index using convex-dual-layer remote phosphor geometry with YOCl:Eu3+
White-light emitting diodes (WLEDs) are semiconductor light sources
whose construction design is usually made up of a single pumping chip and
a single light-conversion film of phosphor compound. The outstanding
problem of this traditional setting…

The better distant phosphor configurations for enhancing WLED color intensity: YVO4:Eu3+ and YF3:Mn2+
The distant phosphor configuration produces more illuminating beams than the
two settings containing conformal or in-cup phosphor. When this configuration
is used, though, it is difficult to manage the color standard of light-emitting
diodes…
