Abstract
⺠A Eu3+, Tb3+ codoped CSH phosphor was synthesized by liquid-phase reaction. ⺠CSH phosphor was heated at 900 °C to obtain Eu3+, Tb3+ codoped amorphous calcium silicate phosphor. ⺠Under 379 nm excitation, this phosphor showed emission peaks at 542 nm and 613 nm. ⺠The luminescent color could be continuously changed from green to red with increasing Eu/Tb atomic ratio. ⺠It was clarified that electron transfer from Tb3+ to Eu3+ is occurring.
