Intense Visible and Near-Infrared Upconversion Photoluminescence in Colloidal LiYF(4):Er(3+) Nanocrystals under Excitation at 1490 nm
We report intense upconversion photoluminescence (PL) in colloidal LiYF(4):Er(3+) nanocrystals under excitation with telecom-wavelength at 1490 nm. The intensities of two- and three-photon anti-Stokes upconversion PL bands are higher than or comparable to that of the Stokes emission under excitation...
