“…Dy 3+ gives rise to the dominating UC in yellow at ≈581 nm (Dy 3+ : 4 F 9/2 → 6 H 13/2 ). Besides, Sm 3+ and Tb 3+ show weak UC in yellow at ≈570 nm (Sm 3+ : 4 G 5/2 → 2 H 5/2 ) and ≈582 nm (Tb 3+ : 5 D 4 → 7 F 4 ) (see Figure b and a) …”

“…Dy 3+ Single : The energy level arrangement of Dy 3+ is not favored for Yb 3+ as sensitizer. The Dy 3+ : 6 F 5/2 level (≈806 nm) with a relatively large absorption cross‐section (≈two times stronger than Er 3+ at ≈806 nm) makes it suitable to be used as an intermediate energy level for UC . For Dy 3+ singly doped UC materials, UC emission in yellow at ≈581 nm (Dy 3+ : 4 F 9/2 → 6 H 13/2 ) and in blue at ≈484 nm (Dy 3+ : 4 F 9/2 → 6 H 15/2 ) shows the strongest and second strongest intensity under excitation at ≈806 and ≈783 nm.…”

The world's plastic production reached 269 million tons p.a. in 2015. The EU fraction of this was 50 million tons, with 40% of this attributed to product packaging. [1] Even though packaging exhibits the highest recycling rate for any plastic product, this recycling rate in the EU is less than 40%. [1,2] Overall, 29.7% of the plastic within the EU was recycled, with the remainder either burnt for energy recovery (39.5%) or dumped in landfills (30.8%). Recently adopted EU legislative proposals on waste management put pressure on the industry to find solutionsThe demand for more efficient and complete sorting techniques for plastic waste is growing, and one possible solution isbased on fluorescent labeling. Novel fluorescent labels based on trivalent lanthanide (Ln 3+ ) activated inorganic up-conversion (UC) materials offer a promising technological solution for plastic recycling. UC is a nonlinear, anti-Stokes process of combining two or more low energy near-infrared (NIR) photons to obtain the emission of a single higher energy photon. While Ln 3+ based UC materials possess one key disadvantage -low quantum yield, they also exhibit many unique features, such as high signal/noise ratio, tailored emission color, long photoluminescent lifetime, and low toxicity. These unique features endear them for a diverse range of applications and offer many new opportunities. Herein, we review the recent advances in the Ln 3+ activated inorganic micro-sized UC materials from the perspective of tailoring UC emission color and intensity for plastic recycling applications.

“…Two peaks at 537 n m and 548 n m were observed. According to the energy level diagram of the erbiu m-doped fiber [10,12,13] shown in Fig. 1, these two peaks were generated by Er 3+ ions decaying fro m the 2 H 11/2 and 4 S 3/2 states to the 4 I1 5/2 state.…”

A stable fiber laser operating at appro ximately 976 n m peak power at a 280 ns and 1.9 W pump was used as a pumping source for an upconversion laser based on an Er 3+ :doped LiLuF4 crystal. A 548 n m wavelength and 320 mW could be achieved. In this study, we used a 976 n m lo w threshold average pump power fiber laser at 8 mW, wh ich can achieve green upconversion laser output at room temperature. Th is system includes a high reflective coating at 552 n m+/-10 n m on the LiLuF4 crystal and a 96% reflective mirror forming a laser cavity fo r the 548 n m laser. Using the laser cavity setup and 976 n m fiber laser pu mp, lo w threshold pump power green erbiu m upconversion lasing was achieved. The two peak wavelengths of 548 n m and 537 n m are observed and the intensity changes by changing the input to 976 n m pu mp power.

“…The conversion of infrared radiation into visible light has attracted much attention for the last twenty five years, especially in lanthanide doped fluoride glasses [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. It leads to a large number of new laser lines, especially in fiber lasers [18].…”

The up-conversion emission of Nd 3+ , Sm 3+ and Er 3+ has been studied in a new halogenoantimonite glass with the chemical composition 80 Sb 2 O 3 -10 ZnBr 2 -10 KCl. Doping concentration was 0.2 mol% of lanthanide (Ln) ions. Rare earths were introduced as fluorides LnF 3 that were further converted into oxides. Main physical properties of base glass were measured, including density, thermal expansion, characteristic temperatures, refractive index and optical transmission. The amount of residual hydroxyls was calculated from the OH absorption band around 3000 nm. The recorded up-conversion emission lines are λ em = 536 nm for Nd 3+ pumped at 805 nm; λ em = 563 nm, 600 nm, 631 nm and 645 nm for Sm 3+ pumped at 945 nm; λ em = 531 nm for Er 3+ pumped at 798 nm. Co-doped glass (0.1 Yb 3+ + 0.1 Er 3+ ) pumped at 980 nm has three emission lines at 524 nm, 545 nm and 650 nm. Corresponding transitions have been identified and the mechanisms ruling the up-conversion process is discussed. They include excited state absorption (ESA), energy transfer (ET) cooperative energy transfer (CET), emission assisted by phonon (EAP), multiphonon relaxation (MR) and cross-relaxation (CR).
