Increasing demand for high brightness LEDs for LCD TV backlighting and solid-state lighting requires MOCVD growth of GaN at high growth rates (>5 μm/h) with high crystalline quality in mass production reactors.

The favorable periods and thickness of InGaN/GaN QWs for high brightness and high EQE under high injection current (above several tens of mA) of blue LEDs are reported [16 18].
A library of ∼100 000 clones was screened for high brightness specifically at emission wavelengths of >650 nm.

White quantum dot light-emitting devices (WQLEDs) are promising candidates for high-brightness, high-efficiency, and color-saturated displays.
Key customers of the 100-kV STEM's saw the advantages of the high brightness source, the cold-field emitter, and contracted VG to extend the design to 300 kV for yet higher brightness and higher resolution.
The demands for new fluorescent probes with higher brightness, photostability, and spectral distinguishability for bioimaging never end.
These guns have been developed through accelerator R&D programmes in the field of high brightness sources for other applications (linear colliders, free electron lasers).
For example, a string of high brightness LED, each operating with 3 V forward voltage and 330 mA forward current, is adopted in ref. [4].
