Photo-luminescence characteristics of binary P₂O₅–CaO glass ceramic

ABSTRACT

To explore excellent colour display materials, the binary phosphate glass ceramics doped with R (R = Tm³⁺, Tb³⁺, Eu³⁺, Sm³⁺, and Mn²⁺) ions were prepared. The X-ray diffraction, transmission electron microscope, absorption, excitation, and emission spectra of the glass ceramics had been studied in detail. It was found that Ca₂P₂O₇ and CaP₂O₆ had excited in the glass ceramics, which can improve the luminescent characteristics of the materials. The results show that the binary phosphate glass ceramics can display abundant colours, which is very helpful for developing the luminescent materials for colour display.
