Changes of fluorescence performances with various ratios of Eu³⁺ to Tb³⁺.

a, Photoluminescence emission spectra of the Eu³⁺ and Tb³⁺ co-doped NLM nanorods under the excitation at 280 nm (total concentration: 5 mol%). b, CIE chromaticity diagram for the emission spectra of the various ratios of Eu³⁺ to Tb³⁺ co-doped NLM nanorods (i: 5% Eu³⁺; ii: 4% Eu³⁺/1% Tb³⁺; iii: 3% Eu³⁺/2% Tb³⁺; iv: 2% Eu³⁺/3% Tb³⁺; v:- 1% Eu³⁺/4% Tb³⁺; vi: 5% Tb³⁺). c, the decay curves of Tb³⁺ in the resulting NLM nanorods. The sample was excited at 289 nm (monitored at 544 nm).
