XRD Development

Prof. Wilhem Rontagen

He was a German physicist had discovered X-rays in 1895

First Nobel Prize (1901)

X-rays were invincible, traveled straight lines, affected photographic film in the same way as light

Max Theodore Felix von Laue

X-rays wavelength = 0.01nm- 10nm

Spacing adjacent atoms = 0.3nm

A crystalline sample cause X-rays diffract (1912)

Same order as atomic spacing in a crystal

Nobel Prize (1914)

Bragg - Father & son

W.L. Bragg produce geometrical interpretation : Angle of diffraction & Interplanar spacing

Quantitative determination of structure of crystalline materials lead in understanding the role of crystal sturcture
