Synthesis of CaSO4:DyCaSO4:Dy, CaSO4:Eu3+CaSO4:Eu3+ and CaSO4:Eu2+CaSO4:Eu2+ phosphors

CaSO4:DyCaSO4:Dy is a well-known phosphor for radiation dosimetry using thermoluminescence. CaSO4:EuCaSO4:Eu, phosphors also find applications in radio-photoluminescence dosimetry and PLLCD. Various syntheses of these phosphors are described and optimum procedures are suggested. Effects of various preparation methods on luminescence characteristics are discussed in terms of elimination of unwanted impurities, grain size, etc.
