Persistent luminescence in Ca8Zn(SiO4)4Cl2:Eu2

A new persistent, green emission is reported for europium activated Calcium Zinc Chlorosilicate (CZCS). The phosphor was prepared by the solid state reaction and characterized using XRD, PL and TL techniques. The decay was characterized by admixture of two exponential components with decay constants...

Beschreibung
Zusammenfassung:	A new persistent, green emission is reported for europium activated Calcium Zinc Chlorosilicate (CZCS). The phosphor was prepared by the solid state reaction and characterized using XRD, PL and TL techniques. The decay was characterized by admixture of two exponential components with decay constants 20.2 and 101s. ► New results on TL and persistent photoluminescence in Europium activated Calcium Zinc Chlorosilicate are reported. ► Intense green emission is observed. ► Long lasting emission observed after 254nm irradiation. ► Two glow peaks at 135 and 170°C observed.
