May 1 , 2012– Light at night is bad for your health, and exposure to blue light emitted by electronics and energy-efficient lightbulbs may be especially so.
Blue light emitted from electronics delays the release of melatonin, which is a hormone that makes you feel sleepy.
Among the most commonly studied ICPs is polyaniline (PANI) due to its ease of synthesis, unique non-redox doping/dedoping chemistry, relatively high conductivity and environmental stability [1], and many technological applications in molecular electronics, light emitting diodes, sensors, actuators, solar cells, light weight batteries and antistatic and anticorrosion coatings [2].
Furthermore, other emerging technologies, such as light emitting diodes, flexible and wearable electronics, as well as electric vehicles, demand novel thermally conductive materials with new attributes (e.g., light-weight and flexible).
This subject has attracted great attention recently because of interest in organic electronics and light emitting diodes [10].
Graphene on SiC produces high-frequency electronics [173], light emitting devices [173], and radiation hard devices [173].
The excitation source of this prototype consists of two high power light emitting diodes (LEDs), visible (LZ4-00MD00, MousElectronicsics, Mansfield, TX) and UV (LZ1-000A00, MousElectronicsics, Mansfield, TX) LEDs.
The interest of both fundamental and applied science was mainly driven by the goal to understand and improve the properties of materials used for organic electronics (e.g., light emitting diodes, field effect transistors and solar cells) and to establish novel systems for optical applications (e.g., waveguiding and lasing).
In a view to desired time modulation and the dual wavelength time division multiplexing, we used light emitting diodes for sources, a phototransistor for the detector, and electronics process the detected signal.
These properties revealed that the ZnO is a useful material in electronics, optics, photonics, room temperature UV lasers, light emitting diodes and sensors [10, 11, 12, 13, 20, 22].
