The phosphors that are able to convert vacuum ultraviolet (VUV) light into visible light are demanded for the development of novel displaying and lighting devices. NaYF4:Pr3+,Dy3+, NaGdF4:Pr3+, NaGdF4:Dy3+ and NaGdF4:Pr3+,Dy3+ were prepared by hydrothermal synthesis method and their luminescent properties in VUV-vis spectral region were investigated at room temperature. For NaYF4:Pr3+,Dy3+, no energy...
The VUV-UV spectroscopic properties of Ce 3+ in Ba 2 Mg(BO 3 ) 2 , Ba 2 Ca(BO 3 ) 2 and Sr 2 Mg(BO 3 ) 2 were compared, and the relation between the energy of the 4f→5d transition of Ce 3+ and the coordination environments of substituted alkaline earth ions was discussed. The chromaticity coordinates of Ce ...
