title = "Improved infrared emissions of Er3+-Tm3+ codoped Al2O3 thin films: The role of cross relaxation among rare earth ions",
abstract = "Er3+-Tm3+ codoped amorphous Al2O 3 thin films were synthesized using pulsed laser deposition and their photoluminescence (PL) properties were investigated. The infrared fluorescence was improved by post-annealing and a broadband emission was obtained. Three cross relaxation channels between Er3+-Tm3+ and Tm-Tm ions were observed for the films with annealing temperature increased from 800 to 850°C, which were further analyzed by deconvoluting the emission spectra using Gauss-fitting method. Our results suggest one possible approach to achieve wideband infrared emissions in the 1.45-1.65 μm wavelength region for the Er3+-Tm3+ codoped systems.",
