Is there a UV lamp (not a synchrotron) that will generate UV light down to say 150 nm? I need a light source to do optical characterization (bandgap measurement as a function of temperature) of a wide bandgap semiconductor (~6.2 eV), so I would prefer a light source below 200 nm, ideally around 150 nm. Is there such a thing?

Thanks.

A google search yielded the following;

Some models go down to 112 nm.

1. What is a 150 nm UV light source?

A 150 nm UV light source is a type of ultraviolet light that emits wavelengths of 150 nanometers. This type of UV light falls within the vacuum UV range and is not visible to the human eye.

2. What are the applications of a 150 nm UV light source?

A 150 nm UV light source is commonly used in scientific research and industrial processes, such as surface analysis, photochemical reactions, and UV spectroscopy. It is also used in medical and forensic fields for DNA and fingerprint analysis.

3. How is a 150 nm UV light source different from other UV light sources?

A 150 nm UV light source emits shorter wavelengths than most other UV light sources, which makes it highly effective for certain applications. It is also unique in that it falls within the vacuum UV range, making it useful for experiments that require a vacuum environment.

4. How is a 150 nm UV light source created?

A 150 nm UV light source is typically created using a mercury vapor lamp or a deuterium lamp. These lamps contain gases that emit UV light when an electric current is passed through them. The emitted light is then filtered to produce a specific wavelength, such as 150 nm.

5. Are there any safety concerns with using a 150 nm UV light source?

Yes, there are safety concerns when working with any type of UV light. 150 nm UV light can cause damage to the skin and eyes, and precautions should be taken to avoid direct exposure. Proper protective equipment, such as goggles and gloves, should be worn when handling a 150 nm UV light source.
