Multiband infrared luminescence of Er3+-Ho3+-Nd3+/Tm3+-codoped telluride glasses
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 4I13/2-4I15/2, 4I11/2 -4I13/2 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.
