Rare earth ion Tb³⁺ doped natural sodium feldspar (NaAlSi₃O₈) Luminescent properties and energy transfer.

ABSTRACT: In this study, Tb³⁺-doped natural sodium feldspar (NaAlSi₃O₈) phosphors have been successfully prepared using high-temperature solid-state method with natural sodium feldspar as a substrate. Energy-dispersive X-ray spectrometry analysis (EDX) of NaAlSi₃O₈ showed that 0.03 wt% of Eu element was present, and elemental distribution mapping analysis showed that the distribution of trace Eu in minerals was aggregated. The crystal structure and luminescence properties of the natural sodium Eu-containing feldspar and synthetic sodium feldspar NaAlSi₃O₈:Eu³⁺, Tb³⁺ phosphors are discussed in detail. The crystal structure analysis of the samples showed that the Na⁺ in the natural matrix was
