The III-nitride light-emitting diodes (LEDs) have popularly penetrated into the market of the visible light communication, lighting, sensing, and display illumination [1,2]. It is well known that the III-nitride LED-based white-lighting source is able to yield the efficacy much higher than those traditional light sources such as the incandescent light bulbs by more than 15 times, which therefore, leads to a yearly reduction of the CO2 emission by 1900 Mt [1], and makes significant contribution to relieve the global warming effect. Additionally, compared to the mercury-based fluorescent light tubes, the III-nitride solid-state lighting source produces no pollutions. As a result, the III-nitride–based solid-state lighting has attracted intense global interest and is regarded as the ultimate lighting solution in this century.
