Interpretation:
The ICP plasmas should be compared to microwave plasmas with respect to their advantages and disadvantages.
Concept introduction:
ICP plasmas or Inductively Coupled Plasmas are a high-temperature source of ion and they ionize, atomize, and decompose the samples. It uses inductively coupled plasmas to produce or form excited ions and atoms which help in emitting
Plasmas generated by microwave are known as microwave plasmas. The magnetrons which generate plasmas are settled outside the plasma. With the help of quartz window, the radiation gets irradiated into the vacuum chamber.

- How does fluorescence work in bulk semiconductors?arrow_forwardA Knudsen cell was used to determine the vapour pressure of germanium at 1000 °C. During an interval of 7200 s the mass loss through a hole of radius 0.50 mm amounted to 43 μg. What is the vapour pressure of germanium at 1000 °C? Assume the gas to be monatomic.arrow_forwardUse the Jablonski diagram to explain why the narrower the band-gap is, the lower the fluorescence efficiency(fluorescence quantum efficiency) in general.arrow_forward
- Discuss the differences between fluorescence and phosphorescence. Draw the jablonski energy diagram. Explain about intersystem crossing and quenching of fluorescence.arrow_forwardUnder what conditions does the extended Debye-Huckel law, equation 8.52, become the Debye-Hckel limiting law?arrow_forward26 24 22 20 18 16 14 12 B 10 10 15 20 Volume (L) 2.00-mol of a monatomic ideal gas goes from State A to State D via the path AB C→D: State A PA=10.5atm, VA=10.50L State B PB=10.5atm, VB=3.50L State C Pc=24.0atm, Vc=3.50L State D Pp=24.0atm, Vp=22.50L Assume that the external pressure is constant during each step and equals the final pressure of the gas for that step.
