Luminescent Particles, Methods and Light Emitting Devices Including the Same

Номер: US20120305955A1
Принадлежит: Individual

A luminescent particle includes a luminescent compound that is configured to perform a photon down conversion on a portion of received light. The luminescent compound includes a host compound material and an activator material that is combined with the host compound material. The activator material is provided in a quantity that limits a conversion efficiency of the luminescent compound to limit a decrease in the decrease in luminous intensity of light emitted from the luminescent compound and thus provide a given color shift of the a combined emission wavelength from a non-excited state to a steady-state excited condition.
