Abstract

See full text

Solid-state lighting devices including light-emitting diodes (LEDs), and more particularly binder materials for light-emitting devices are disclosed. A lumiphoric material for a light-emitting device may include lumiphoric particles embedded within a binder material. The lumiphoric material may be formed according to sol-gel chemistry techniques where a solution of binder precursors and lumiphoric particles is applied to a surface, dried to reduce liquid phase, and fired to form a hardened and dense lumiphoric material. The binder precursors may include metal oxide precursors that result in a metal oxide binder. In this manner, the lumiphoric material may have high thermal conductivity while also being adaptable for liquid-phase processing. In further embodiments, binder materials with or without lumiphoric particles may be utilized in place of conventional encapsulation materials for light-emitting devices.
