The aim was to design a multi-chromatic phosphor based on the colour mixing principle, whereby white light can be produced from an appropriate mixture of blue, green, and red emissions by a single phosphor. In this perspective, Tm2O3, Tb4O7, and Eu2O3 were simultaneously doped in single host glass matrix. A series of Tm2O3 single- as well as Tm/Tb/Eu triple-doped glasses were synthesised. The photoluminescence...
Tb3+ single- and Tb3+/Eu3+ double-doped borate as well as fluorozirconate glasses are investigated for their photoluminescence and energy transfer properties based on the concentration of the dopants. All the double-doped glasses consist of a constant concentration of 0.5at% Tb3+ ions and an increasing Eu3+ ions concentration, ranging from 0.05 to 0.5at%. Upon direct excitation of only Tb3+ at 485nm,...
