Produktbeschreibung
The spectral analysis techniques have been applied to magnesium doped calcium sulphate and MgMo3O2H7 samples. It has been finds confirm by XRD analysis. Nanoparticles of CaSO4: Mn with size around 25 -40 nm, were synthesized by the combustion method. With the advent of newer techniques for dose reduction coupled with the development of more sensitive detectors, the radiation doses in radiological medical investigation are decreasing. This paper gives the account of the development of a new and sensitive phosphor CaSO4: Mn and its characterization. The PL excitation spectra of Mn2+ showed four intense peaks in the wavelength region 252 nm. These spectra showed that the greatest absorption for Mn2+ emission cover a region from 552 nm, 761 nm, 1010 nm. Approximately I concluded that these materials are emitting the green-reddish light applications.
