Maybe my question is classic, but I need simple idea in order to select the target tube of XRD with materials to be tested!
Cu is popularly used and availability is good. Relatively strong beam intensity can be obtained. The wavelength of CuK(alpha) radiation is 0.154 nm.
If you need smaller wavelength to obtain more diffraction spot, you can select Mo target. In this case, the wavelength is 0.071 nm.
Thank you Masatoshi,
Is there any standard in order to select the target , for example between Mo-target or Cr-target? or just depends on arability !
Depend on ur sample.
Example:
Cu for material that contain high Fe or Co will floresences.
Cr is for large d-spacings (clays, organic materials, zeolites), but High attenuation in air.
Mo is for single crystal, small unit cells (metals)
