Photoluminescence properties of La(PO3)3:Tb3+ under VUV excitation

La1−x(PO3)3:Tbx3+ (0

A strongest band around 174nm, observed in the excitation spectrum of La0.55(PO3)3:Tb0.453+, indicates that La0.55(PO3)3:Tb0.453+ can efficiently absorb the vacuum ultraviolet (VUV) energy. The band overlapping around 210 nm implies that the excited energy can be efficiently transferred from VUV to UV region. Therefore, La0.55(PO3)3:Tb0.453+ is a promising phosphor in VUV region.Figure optionsDownload as PowerPoint slide
