“…3 is the digital image of NLZ6 sample under excitation of 0.25 mW 808 nm laser, and the green upconversion emission is strong to be seen by naked eyes. The red emission may be attributed to 4 states. However, the green emissions reach the "saturation" state when the concentration of codoped rare earth ions is larger than a certain threshold.…”

“…NaYF 4 has the highest upconversion luminescence efficiency at present, but its preparation process needs fluorinated raw materials which are harmful to the environment. What is more, its poor machinability and chemical stability limit the application of fluoride upconversion luminescence materials.…”

Er 3+ /Yb 3+ codoped niobium pentoxide glasses were fabricated by the aerodynamic levitation (ADL) method with rapid cooling rate. All samples with various doping concentrations showed good upconversion luminescence properties under 980 nm laser excitation. The structure, transmittance spectrum, and luminescence properties of the samples were systemically investigated by XRD, UV-Vis-NIR spectrophotometer, and upconversion spectra. All transparent samples exhibited green and red upconversion emissions centered at 532, 547, and 670 nm. Experimental results showed that the sample codoped with 1 mol% Er 3+ /Yb 3+ has the strongest upconversion emissions, and the increase of the doped Yb 3+ concentration results in the increased red emission and reduced green emission. The logI-logP plot of green emission indicated that the green emissions reach the saturation at high pump power excitation, deviating from the low-power regime. After one-photon energy transfer (ET) process, 4 I 11/2 + 4 I 11/2 → 4 F 7/2 + 4 I 15/2 process between the two neighboring Er 3+ ions was responsible for the population of the 4 S 3/2 / 4 H 11/2 states. The niobium pentoxide codoped with Er 3+ /Yb 3+ bulk glasses could be used in the dye sensitized solar cell (DSSC) to improve the efficiency.

“…However, there is a heavy limitation for the application of powder NaYF4 in optical amplifiers and solid-state laser. Hence, NaYF4 transparent glass ceramic is considered as a good candidate for practical application due to its good spectroscopic properties, chemical and mechanical stability [4][5][6][7].…”

Fluoroaluminosilicate glass-ceramics with M 1 − x R x F 2 + x (M 2+ : Sr 2+ , Ba 2+ , R 3+ : rare earth ions) crystals are novel host materials for luminescence applications. However, the preparation of such materials is still a trial-error based approach due to the lack of detailed glass structure understanding. In this work, the authors study the phase separation and potential nanocrystal formation in a series of Ba 2+ and La 3+ containing fluoroaluminosilicate glasses by molecular dynamics (MD) simulations. Fluoride phase separation is observed from all simulated glass samples. With gradual LaF 3 to BaF 2 substitution, the cations enrichment changes from Ba 2+ , to Ba 2+ and La 3+ , and finally La 3+ in the fluoride-rich regions. Besides, the competition between Al 3+ and La 3+ in fluoride phase and the consequently redistribution of Al 3+ and Na + into oxide phase are observed, which can change the local environment of luminescent centers, affecting luminescence. An experimental support to this phenomenon is given. Therefore, MD simulation with effective potentials can be a practical method to study the structural origins of nanocrystal from fluoride phase separation as well as to study the structure-property relationship in fluoroaluminosilicate glass. The simulation driven glass structure and crystal phase exploration can thus become an effective method in designing glass-ceramics for luminescence and other applications.
