nm

**Calculation Tutorial:**

**STEP1:** Open the XRD graph of the material, which is obtained from the instrument.

**STEP2: **Now zoom on the area for which you want to calculate the d value and note down the angle at which peak is shown.

**STEP3: **Now enter the measured Peak Position (i.e. 31.8 degree) in “Peak Position (2 Theta)” column of the calculator. You should get the calculated results of the d value in the “Calculated Result” field.

**NOTE: Default value of wavelength of LASER is set is 0.15418, which is mostly used in the instruments; and Order of Reflection is 1. You can also change these values as your desire if you want.**

**Theory Behind Calculations:**

X-Rays are having wavelength between 0.01nm to 10nm. Hence X-Rays can penetrate inside the crystal structure of any material very easily; and tells us the properties of material while coming out from that material. Which is why X-Ray spectroscopy is very useful technique for characterization of different types of materials.

**Bragg’s Law:**

Order of Reflection (n) × Wavelength (λ) = 2 × Interplanar spacing (d) × Sinθ

So, Interplanar spacing can be calculated easily from the formula as:

**Interplanar spacing (d) = Order of Reflection (n) × Wavelength (λ) / 2 × Sinθ**

very useful thanks

how could I calculate theam??

I wonder the exact equation about that

what will be effect if d spacing is increasing as concentration of dopinf increases

Very interesting.Thank you.

that is what I really looking for thank you..

why lattice parameters important and what these values tell us while characterization

We do not spend much time thinking. Thank you to the author of this site.
