摘要：

A series of BaSiF6-based rare-earth down-conversion phosphors have been firstly hydrothermally prepared and characterized. Under ultraviolet radiation excitation, BaSiF6:Eu3+ phosphors show the characteristic f-f transitions of Eu3+ and give a bright orange-red emission. We found the luminescence quenching concentration was 15%, which is relatively high. To further enhance the luminescence, K+ was added as a charge compensator. Furthermore, cold white colour can be obtained by co-doping Tb3+ ions.
