Synthesis and luminescence properties of Yb3+–Er3+ co-doped LaOCl nanostructures

A Novel Scheme to Obtain Y2O2S:Er3+ Upconversion Luminescent Hollow Nanofibers via Precursor Templating

“…4 I l5/2 of Er 3+. 41,42 (4) CIE Analysis In general, color can be represented by the Commission International de L'Eclairage (CIE) 1931 chromaticity coordinates. The color coordinates for the green emission in the present experiment are calculated based on the corresponding upconversion emission spectra and the results are shown in Fig.…”

Atomic/molecular layer deposition of hybrid inorganic–organic thin films from erbium guanidinate precursor

“…[1][2][3][4] In particular, Er 3+ with its specific emission at ~1500 nm is used as a dopant in optical silica fiber amplifiers to overcome their loss window of infrared wavelengths. [5][6][7][8][9][10][11] In fact, however, the absorption coefficient of Er 3+ ions is too low for practical utilization. Sensitizing the Er 3+ emission by complexation with strongly lightabsorbing organic antenna ligands, e.g.…”

Stability field diagrams for Ln–O–Cl systems

“…LaOCl is a good host for the smaller lanthanide ions. When LaOCl is co-doped with Er 3+ and Yb 3+ ions, it can produce strong green and red up-conversion emission at 526, 548 and 671 nm on excitation by a 980 nm diode laser [7]. LaOCl:Eu 2+ is a blue-emitting phosphor [8].…”
