摘要 | Using CaO/CaCO3 (blend) and NH4Cl as the respective calcium and chloride sources, we have succeeded in the synthesis of single-phase Ca2SiO3Cl2:Eu2+ powder phosphor via solid-state-reaction. Indeed, two emission bands due to Eu2+ should be observed in Ca2SiO3Cl2:Eu2+, since there are two Eu2+ luminescence centers substituting for two Ca2+ sites. However, interestingly, only one emission band centered at 495 nm is observed. This is explained based on the uniform covalency and crystal field of two Eu2+ sites. The excellent thermal stability and the intense emission upon near-ultraviolet (UV) light excitation suggest that Ca2SiO3Cl2:Eu2+ can be used as a potential bluish-green phosphor for near-UV white LEDs.
