A program for improving the efficiency of the light emitting diode

A process for improving the external quantum efficiency of a light emitting diode (LED) is provided by exposing one or more components of an LED, a partially assembled LED, or a completely assembled LED to an amount of hydrogen or hydrogen gas, or to an atmosphere containing higher quantities of hydrogen or hydrogen gas for a period of exposure time. Kits and processes for constructing a light emitting diode having an improved external quantum efficiency is further provided, which includes exposing one or more components of an LED, a partially assembled LED, or a completely assembled LED to an amount of hydrogen or hydrogen gas, or to an atmosphere containing higher quantities of hydrogen or hydrogen gas for a period of exposure time.
