Synthesis and Nd3+ Luminescence Properties of ALa(1-x)Nd(x)P(4)O(12) (A = Li, Na, K, Rb) Tetraphosphate Nanocrystals

Abstract : The nanocrystalline alkali tetraphosphates doped with Nd3+ ions were synthesized using the coprecipitation method. The structural and spectroscopic properties of ALa1–xNdxP4O12 (A = Li, Na, K, Rb) nanocrystals were shown. The impact of the dopant concentration on the emission spectra and the kinetics of the 4F3/2 excited state was analyzed. The exponential decay profile for each of the Nd3+ concentrations was discussed in terms of fast energy diffusion with reduced cross-relaxation processes. The comparison of luminescent properties for different alkali cations was presented.
