Micromechanical properties of Dy3+ion-doped (LuxY1-x)3Al5O12 (x=0, 1/3, 1/2) single crystals by indentation and scratch tests

Ming Liu et al.

Summary: The influence of Lu ion on the micromechanical properties and fracture behavior of Y3Al5O12 single crystals (YAG) was investigated by conducting indentation and scratch experiments on three different kinds of Dy3+ ion-doped (LuxY1-x)3Al5O12 (x = 0, 1/3, 1/2) single crystals. The highest (or lowest) values of hardness, elastic modulus, and fracture toughness were observed for x = 1/3 (or 1/2). The indentation size effect was explained using four different models, with the Hays-Kendall approach being the most accurate in determining the true hardness. The fracture toughness values obtained by the Vickers hardness method agreed with those obtained by scratching with a spherical indenter based on linear elastic fracture mechanics.

Structure and fluorescence characteristics in highly Dy3+doped tellurite-fluoride glass for white light fiber lasers

Jilong Cao et al.

Summary: High concentration Dy3+ doped tellurite-fluoride glasses were synthesized, and their structure and radiation properties were evaluated. The addition of high concentrations of DyF3 resulted in a wide fluorescence bandwidth and excellent stimulated emission characteristics. The yellow/blue value enhanced with the addition of DyF3, possibly due to the depolymerization of [TeO4] and inversion of Dy3+ symmetry. The glass showed relatively large emission cross-section and gain coefficient, indicating its potential as a gain material for white light fiber lasers.

Up-conversion charging of a Tb3+-activated garnet phosphor

Tingxing Shi et al.

Summary: This study reports, for the first time, the up-conversion charging process of Tb3+-activated garnet phosphor, Gd3Ga5O12:Tb3+, using a 488 nm laser as the excitation source. The 4f(7)5d state of Tb3+ is excited by absorbing two excitation photons, followed by the charging of the phosphor. Spectroscopic investigations reveal that an energy-transfer mechanism dominates the up-conversion excitation. This work provides a new strategy for charging Tb3+-activated phosphors with up-conversion, expanding the scope of persistent phosphors.

Jinhai Zou et al.

Summary: The research team successfully demonstrated watt-level high-power yellow laser generation using Dy3+-doped ZBLAN fiber. They found that the reflectivity of the output coupler and the length of the gain fiber have significant impacts on the performance of the yellow laser, achieving a maximum efficiency of 33.6% and a maximum output power of 1.12 W. The study shows the potential of yellow Dy3+-doped ZBLAN fiber lasers in ophthalmology, astronomical exploration, and high-resolution spectroscopy applications.

The investigations of Dy:YAG and Dy,Tb:YAG as potentially efficient GaN blue LD pumped solid state yellow laser crystals

Shoujun Ding et al.

Summary: With the successful growth of high-quality Dy:YAG and Dy,Tb:YAG crystals using the Czochralski method, their potential as competitors for all solid state yellow lasers is highlighted. Co-doping Tb3+ into Dy:YAG crystal improves its emission crosssection, while the high thermal conductivity of Dy:YAG suggests its suitability for high-power laser operation. Both Dy:YAG and Dy,Tb:YAG show promise in accelerating the population depletion on the lower laser level of Dy3+, making them excellent candidates for yellow laser applications.

Tao Hu et al.

Summary: Host-sensitized rare-earth-ion lighting has shown promise in achieving single-phase white-light emission by overcoming self-absorption issues within multiple phosphors.

By adjusting the exciton behaviors and host-sensitized emission, this phosphor exhibited excellent thermal stability and high energy transfer efficiency.
