Blue Led Diodes
light emitting diode?
in circuit which each leds in parallel,the red led starts to emit light before the blue and green one. why? and how leds give colorful light although they are white?
Different color LED's are made using different materials. This is very different from colored bulbs that are simply white light that is filtered. Therefore different color LED's have different characteristics including break over voltage

The Blue LightEmitting Diodes $114.71 In this book, I have optimized the growth of n and pGaN films, and high quality InGaN/GaN multiple quantum wells (MQWs) on sapphire (0001) substrate by a low pressure metalorganic chemical vapour deposition and have fabricated high brightness InGaN/GaN MQW lightemitting diodes (LEDs) under optimum conditions. To improve quantum efficiency which is generally poor in the conventional rectangularshaped QWs due to spatial indirect recombination induced by internal piezoelectric field, we proposed a possibility of quantum dot (QD) engineering with triangularshaped band structure in the InGaN/GaN QWs. The structural and optical properties of the InGaN/GaN MQWs with different threading dislocation densities were also investigated. The effects of Sidoped nGaN and Mgdoped pGaN layers on the electrical and optical properties of the InGaN/GaN MQW LEDs were investigated and optimized under various growth parameters.

The Diodes $93.99 High Quality Content by WIKIPEDIA articles The Diodes were a Canadian punk/new wave band formed in 1976. They released five albums: Diodes (1977), Released (1979), ActionReaction (1980), Survivors (1982), and Time/Damage Live 1978 (2010). One of the first Toronto bands playing that style of music, The Diodes helped foster the scene in the city. Along with manager Ralph Alfonso, The Diodes opened the first Canadian punk nightclub in 1977, called Crash n Burn, where many of the citys punk bands at that time played. The first band to play the club was The Nerves, on a double bill with The Diodes. The club was closed at the end of the summer of 1977 due to complaints by the Liberal Party of Ontario (the principal tenants of the building).

Red and Near Infrared Microcavity LightEmitting Diodes $196.21 Lighting is essential to modern society but it accounts for nearly 20 of the electrical energy usage. Thus efforts to increase the conversion efficiencies of light sources are attracting more and more attention. Potential high efficiency light sources are fluorescent lamps or lightemitting diodes (LEDs). Modern LEDs show internal quantum efficiencies of virtually 100 . However, in the case of standard LEDs most of this light is trapped inside the device because of total internal reflection at the interface semiconductorair. Several methods have been developed in order to increase the extraction efficiency. This can be done either by optimizing the device geometry in order to increase the escape cone or by incorporating a resonant structure in order to force the internal emission into the existing escape cone. The latter approach is called microcavity LED (MCLED) or resonant cavity LED (RCLED) and is presented in detail in this work. Novel concepts to further increase the external quantum efficiency are discussed and experimental results are presented.

How to make my sonic screwdriver open doors....?
okay, so i found this as a comment on instructables:
"there is a way to open doors with a sonic screwdriver, but it would be destructive. I am talking about inserting a blue laser diode instead of the black light LED, then it can open certain locks. Simple locks, cheap locks, but still 
"
now, it's totally nerdy of me, but i can't stop thinking about this possibility! do you think it's possible? if anyone has any ideas, instructions or websites i could go to, please tell me. i'm willing to experiment myself, but it would be a lot faster if i didn't have to. thanks!
