Abstract

Er 3+ -Tm 3+ codoped amorphous Al 2 O 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 Er ...
