Various factors play a part in the energy consumption of a building : its physical properties, the equipment installed for its functioning (the heating, ventilation and air-conditioning system, auxiliary production of electricity or hot water), the outdoor ...
This brief review describes applications of cyclometallated iridium complexes for energy saving organic light-emitting devices (OLED's) and energy generating molecular photovoltaic cells. The first part consists of a short overview of the methods to modula ...
A method is proposed to estimate objectively occupants' visual discomfort in small office rooms as a function of the illuminance at one or more locations. Expressed as a visual discomfort probability, it is based on an analysis of the past history of the u ...
Trivalent lanthanide ions display fascinating optical properties. The discovery of the corresponding elements and their fist industrial uses were intimately linked to their optical properties. This relationship has been kept alive until today when many hig ...
A new, but archetypal compound [ Ir( ppy- F-2) (2)Me(4)phen] PF6, where ppy- F2 is 2-(2',4'- fluorophenyl) pyridine and Me(4)phen is 3,4,7,8- tetramethyl- 1,10- phenanthroline, was synthesized and used to prepare a solid-state light-emitting electrochemica ...
Recent work on polariton-polariton scattering in semiconductor microcavities under continuous wave excitation conditions is reviewed. For weak non-resonant laser excitation, a marked bottleneck in the polariton distribution is observed, but which is suppre ...
Lanthanide ions possess fascinating optical properties and their discovery, first industrial uses and present high technological applications are largely governed by their interaction with light. Lighting devices (economical luminescent lamps, light emitti ...
We propose a self-commissioning, user-adaptive blinds and electric lighting controller for small office rooms. Self-commissioning, in this context, means that the controller builds an internal representation of the room, in particular of the room's dayligh ...
