Vis and nir photoluminescence of Y1.8Er0.2O3 selectively pumped in erbium energy levels 2H11/2, 4F9/2

Erbium-substituted yttrium oxide Y1.8Er0.2O3 was hydrothermally obtained and optically examined. Steady state photoemission was detected in the VIS and NIR spectral range. The system was selectively pumped with green and red lasers (λem-532, 655 nm) for population of the manifolds 2H11/2 , 4F9/2 of...
