The luminescence properties of K 3 Tb(PO 4 ) 2 activated by Eu 3+ were studied at excitation over the 120–300 nm wavelength range. It is demonstrated that Tb 3+ ions, exhibiting a strong absorption band in the vacuum‐ultraviolet (VUV), can provide efficient sensitisation of Eu 3+ emission in this wave length range, giving rise to intense red luminescence at 150 nm excitation. A proof is given for the concept of VUV sensitisation enabling the engineering of luminescence materials with enhanced conversion efficiency of VUV radiation into visible light.
