Abstract

Luminescent properties of single and co-doped samples of sol-gel polycrystalline BaTiO₃ with trivalent Er³⁺ and Yb³⁺ ions are reported. Under 520 nm pumping, visible radiative emission from ²H_7/2, ⁴S_3/2 →⁴I_15/2, and ⁴F_9/2 →⁴I_15/2; and near infrared emission from ⁴S_3/2 →⁴I_13/2, ⁴I_11/2 →⁴I_15/2 and ⁴I_13/2 →⁴I_15/2 of Er³⁺ and from ²F_5/2 →²F_7/2 of Yb³⁺ ions were measured. For single Er³⁺ doped samples, concentration quenching was observed from the ⁴S_3/2 state, whereas emissions in the 1.0 and 1.5 μm regions increase with concentration due to the cross-relaxation mechanism ⁴S_3/2 +⁴I_15/2 →⁴I_9/2 +⁴I_13/2. Upon addition of Yb³⁺ ions quenching is enhanced, as corroborated by the luminescence decay time curves and emission spectra. This is so because an additional non-radiative energy transfer process from the thermally coupled states (²H_11/2, ⁴S_3/2) of Er³⁺ to the ²F_7/2 state of Yb³⁺ takes place.
