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
Nobel Prize (1914)
