SUMMARY

Creating a fluorescent lamp using krypton instead of neon or mercury is not feasible due to the fundamental differences in how these gases operate. Mercury vapor is essential for producing significant UV light, which excites phosphors to emit visible light. Neon and krypton are classified as discharge lamps rather than fluorescent lamps, and while krypton discharge lamps are commercially available, they are prohibitively expensive. The discussion emphasizes that the principles of operation differ significantly between these types of lamps.

PREREQUISITES
  • Understanding of gas discharge principles
  • Knowledge of UV light generation and phosphor excitation
  • Familiarity with lamp types: fluorescent vs. discharge lamps
  • Basic principles of gas behavior under varying pressures and voltages
NEXT STEPS
  • Research the properties of krypton discharge lamps
  • Study the differences between fluorescent and discharge lamps
  • Explore the production and applications of UV light in lighting technology
  • Investigate the costs and uses of krypton in various industries
USEFUL FOR

Electrical engineers, lighting designers, and anyone interested in the physics of gas discharge and lamp technology.

Could you make a fluorescent lamp with krypton instead of neon or mercury? The wavelength doesn't really matter its just if its actually possible and if it is what pressures and voltages should be used.
 
Physics news on Phys.org
Wavelength absolutely matters. Mercury vapor is used because it produces a lot of UV light when excited by a current. The UV excites the powdered phosphors that coat the inside of the tube, which then glow with a spectrum that appears white to the eye. I don't think neon and krypton lamps do the same.
 
i meant it doesn't really matter to me, but think neon and mercury lights work on the same principal you just add differend additives to shift the wavelenghts. But my question was: if you can make a neon lamp /which you can/ how differend would be the properties and requirements of krypton lamp
 
Neon and mercury are not fluorescent lamps. They are discharge lamps. You can buy a krypton discharge lamp commercially. They are extremely expensive - as is krypton.

Hey, money is no object when you are trying to kill superman. ;)

thanks...any other use for krypton?

Aside from the difference between fluorescence and ionization (arc lamps ionize the atoms)-
