If I recall correctly (big if, high school physics was a while ago), the colour of non-phosphor coated LEDs is dictated by the band-gap of the electrons of the material used. Cooling the material means that there is less thermal energy in the electrons meaning that when excited by applying power they can jump higher and when dropping back release a more energetic photon (thus shifting colour towards a higher frequency).
@Scrogan2 жыл бұрын
I don’t think electrons can jump higher because of a lack of thermal energy. Rather, an increasing band-gap causing the electrons to require more energy to cross the junction makes more sense to me. A quick bit of reading suggests that cooling the semiconductor makes the crystal lattice more rigid; it makes the inter-atomic bonds stronger. These stronger bonds mean an electron needs to be given more energy to break free of the valence band into the conduction band. The forward voltage of the LED will increase as a consequence of this.

Man, I did this experiment years ago in high school when I used to present for science shows in the district. Another cool secondary trick is once you've cooled the LED, you can often drive it with much higher voltages (4-10V instead of the typical 2-3V) without immediately killing the LED due to the cold temperatures, and the additional voltage can excite extra states that also alter the colour output further.

@marc-andreservant2012 жыл бұрын
@@eurybaric That's true, and there's also the additional issue of thermal noise. You don't want the infrared radiation from the sensor's own emission, you only want the radiation from the subject. That also allows you to see colder objects accurately (the signal-to-noise ratio is improved for all wavelengths, not just shorter ones).

@spiderdude20992 жыл бұрын
@@patmelsen no, it’s not like colored incandescent bulbs, the color actually comes from electrons hopping from one type of semiconductor type another that have been “tuned” to have a specific energy barrier. This barrier cannot be crossed until the electrons in one of the semiconducting plates reaches high enough energy to jump into an excited state and across the gap to the other semiconductor. When it jumps to the other semiconductor it wants to go back to its ground state, and so releases a photon of a specific wavelength. The reason the liquid nitrogen changes the color is because cooling the semiconductor increases the amount of energy required to jump the gap. That’s also why it changes from yellow (lower wavelength) to green (higher wavelength). You will never get a color that is lower in wavelength from cooling a LED like this. It always has to be a higher wavelength because the energy must become greater to jump the gap.

@@WASWERTYU temperature does not change the bandgap, if anything lowering the temp will redshift emission because carriers will recombine exactly from the band edge as they don't have enough thermal energy to reach higher energy states in the conduction and valence bands. This blueshift is due to freeze out of Ga defects which emit in a very broad peak centered around 600 nm, which make the emission of a green LED appear more yellow.
