Broken]In summary, the addition of boron in a diamond crystal creates an energy gap of 0.4 eV above the valence band, resulting in a blue color. A quantitative description of the process is not readily available, but a statement by Professor Donald Sadoway from MIT provides a reference for this concept.

Why is a boron doped diamond xtal blue ?

hello :)

Unfortunately I am not able to find the quantitative description of how a concentration of 1ppm Boron doped in a diamond crystal can produce a blue color such as the http://en.wikipedia.org/wiki/Hope_diamond" ?

The doped boron creates an energy gap of 0.4 eV above the valence band.

I will be really thankful for a quantitative description of the process.

Thanks in advance.

You have a reference for this?

1. Why is a boron doped diamond xtal blue?

Boron is a type of impurity that can be found in diamonds. When it is present in a diamond's structure, it absorbs red light and reflects blue light, giving the diamond a blue color.

2. Is a boron doped diamond xtal considered a natural or lab-grown diamond?

A boron doped diamond xtal can be either natural or lab-grown. Natural boron doped diamonds are extremely rare, while lab-grown ones are more common and can be created in a controlled environment.

3. How is boron doped diamond xtal different from other colored diamonds?

Boron doped diamond xtals are different from other colored diamonds because their color is caused by an impurity rather than structural defects or other elements. This makes them unique and highly sought after by collectors.

4. Can the blue color of a boron doped diamond xtal fade over time?

No, the blue color of a boron doped diamond xtal will not fade over time. The color is permanent and will not change or fade due to exposure to sunlight or other environmental factors.

5. What are the uses of boron doped diamond xtals?

Boron doped diamond xtals have many industrial and scientific uses, including as semiconductors in electronic devices, as cutting tools in the aerospace industry, and as radiation detectors in medical imaging. They are also used in jewelry as rare and valuable gemstones.
