Despite this complexity, the photon emission properties of quantum dots were hitherto believed to be like traditional atoms, where a point-emitter description is sufficient. Due to their mesoscopic dimensions, however, the point-emitter description is revealed to break down by comparing photon emission from quantum dots with opposite orientations relative to a metallic mirror. Located in media The Brilliant Mix concept in the CIE color space Located in media Principles of color mixing: The Blue-yellow concept is the standrd solution for phosphor converted white light, the "Brilliant-Mix" concept uses a green shifted phosphor concersion and adds amber to generate white light with high CRI Located in media OLED laboratory-sample from Osram Located in media The method for epitaxial growth of 3-D photonic crystals. [Graphic by Eric Nelson] Located in media Using an epitaxial approach, researchers developed a 3-D photonic crystal LED, the first such optoelectronic device. [Graphic by Eric Nelson] Located in media ory setup for a warm white LED achieves a peak value of 142 lm/W directly on the Planckian curve at 2700 K; an optimized setup at 3000 K could achieve 160 lm/W Located in media World record in the OSRAM laboratory: 201lm/W – 61% efficiency (WPE) Located in media < Previous 10 items 1 ... 1104 1105 1106 1107 1108 1109 1110 ... 1507 Next 10 items > Subscribe to an always-updated RSS feed.
