Could you make a fluorescent lamp with krypton?

    Could you make a fluorescent lamp with krypton instead of neon or mercury? The wavelength doesnt really matter its just if its actually possible and if it is what pressures and voltages should be used.

    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 doesnt 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.

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