(Informa Healthcare, 2011-05-01)
Objective. To evaluate the effectiveness of the color change of hybrid light-emitting diode (LED) and low-intensity infrared diode laser devices for activating dental bleaching and to verify the occurrence of a color ...
Efficient green-emitting Tb3+-doped di-ureasil coating phosphors for near-UV excited light-emitting diodes
(2020-03-01)
Light-emitting diodes (LEDs) are replacing conventional lighting sources, like incandescent and fluorescent lamps, due to their higher efficiency, lower energy consumption and environmental friendliness characteristics. ...
Absorbance detector for high performance liquid chromatography based on a deep-UV light-emitting diode at 235 nm
(2017-08-25)
In this communication, we describe a flow-through optical absorption detector for HPLC using for the first time a deep-UV light-emitting diode with an emission band at 235 nm as light source. The detector is also comprised ...

(2021-01-01)
Nowadays, flexible organic electronics are under intense investigation for environmentally friendly and biocompatible applications. One of the main components of electronic devices is the substrate, which gives support for ...
Encapsulants for light-emitting diodes from visible light-cured epoxy monomers
(Wiley, 2013-01-16)
During the last decade, light-emitting diodes (LEDs) have replaced incandescent, fluorescent, and neon lamps due to their ability to produce high luminosity at low currents and voltages. LEDs are currently encapsulated by ...
Effect of curing time on the bond strength of a bracket-bonding system cured with a light-emitting diode or plasma arc light
(European Orthodontic SocietyPorto Alegre, 2011)
The purpose of this study was to assess the influence of two light units, a light-emitting diode (LED) and a plasma arc light (PAC), on the shear bond strength (SBS) of brackets bonded to enamel. Ninety bovine teeth were ...
