Four-color laser white illuminant demonstrating high color-rendering quality

July 4, 2011 [singlepic id=980 w=320 h=240 float=right]Solid-state lighting is currently based on light-emitting diodes (LEDs) and phosphors.  Solid-state lighting based on lasers would offer significant advantages including high potential efficiencies at high current densities. Light emitted from lasers, however, has a much narrower spectral linewidth than light emitted from LEDs or phosphors.  Therefore it [...]

InAs Quantum Dot Transitions

March 1, 2011[singlepic id=364 w=320 h=240 float=right] The fundamental interaction governing light emission from semiconductor materials is the coupling between electronic states in the semiconductor and a local electromagnetic field. The current generation of solid-state lighting devices operates in the so-called “weak-coupling” regime, in which the rate of energy transfer between the electronic states and [...]
