Multiband infrared luminescence of Er³⁺-Ho³⁺-Nd³⁺/Tm³⁺-codoped telluride glasses

Abstract

This paper reports the simultaneous emissions around 1.53, 1.80, 2.10, 2.70 and 3.00 μm in Er³⁺-Ho³⁺ -Nd³⁺/Tm³⁺-codoped telluride glasses upon excitation of a conventional 808 nm laser diode. Both emission bands of 1.53 and 2.70 μm were assigned to the transitions of ⁴I_13/2 -⁴I_15/2, ⁴I_11/2 -⁴I_13/2 of Er³⁺ ions, respectively, the emission near 1.80 mm was assigned to the transition ⁴F₄ -⁴H₆ of Tm³⁺ ions, and the emissions at 2.10 and 3.00 mm arose from the transitions of ⁵I₇ -⁵I₈, ⁵I₆ -⁵I₇ of Ho³⁺ ions. The materials are promising for ultra-broad band amplified spontaneous emission optical sources at near and middle infrared region.
