Multi-wavelength optical encoding enabled by excitation-dependent luminescence in rare-earth activated La2O3 phosphors

Multifunctional luminous phosphors with controllable emission properties have been developed in response to the increasing demand for improved photonic and optical security systems. Here, urea was used as fuel in a simple combustion process to create Tm 3+ , Er 3+ , and Tm 3+ /Er 3+ activated La 2 O 3 p...
