【 摘 要 】

Luminescence property of a new halo silicate phosphor, X₅SiO₄Cl₆:Tb³⁺ (X = Sr, Ba) prepared by modified solid state method is reported here. It is characterized by powder X-ray diffraction and studied by photoluminescence excitation and emission spectra. In the emission spectra of X₅SiO₄Cl₆:Tb³⁺ (X = Sr, Ba) phosphor, characteristic blue and green emission peaks are present corresponding to Tb³⁺ intra 4ð‘�?? transition. Emission spectrum shows a dominant peak at 544 nm due to the ${}^{5}D_{4} ightarrow {}^{7}F_{5}$ transition of Tb³⁺.
