High light output intensity of titanium dioxide textured light-emitting diodes

Solid-State Electronics, 2008
Abstract Higher light output intensity and wider polar radiation pattern of InGaN/GaN multiple quantum well (MQW) light-emitting diodes (LEDs) with a different nanoscale titanium dioxide (TiO2) textured densities film have been observed. The light output power values and external quantum efficiency of the conventional LEDs at an injection current of ...

Comparison of the Light Output of Image Intensifier Tubes

Radiology, 1961
Image intensifiers are now beyond the realm of experimentation and have become an integral part of the routine equipment in diagnostic radiology. Since the day of W. E. Chamberlain's Carman Lecture, “Fluoroscopes and Fluoroscopy” (1), the need for raising image brightness to cone vision level has been generally recognized.
