Luminescent ions doped materials have been widely applied in many areas, both scientifi c research and practical fi elds. Recently, incorporating luminescent ions and advanced materials into versatile and multifunctional systems seems to be a tendency, motivated by the stimulating desires of fundamental studies and technological applications. This feature article provides a general overview of the myriad of luminescent ions-based advanced composite materials recently investigated. It is demonstrated that the improved or additional properties may be achieved via implementing a strategy of incorporating luminescent ions (lanthanide, transition and main group metal ions) into various types of materials, such as fl exible polymers, two-dimensional atomically thin layers, porous materials, and so on. We outline the design principles, synthesis and processing of various systems joined by luminescent ions doped phosphors. A number of recent works indicate that those novel composite materials allow one to conceive and develop multifunctional applications in a broad area, including optoelectronics, photonics, clean energy, biomedicine, and new types of sensors. Lastly, some challenging issues are discussed and potential directions are suggested for further developing advanced composite materials incorporated with luminescent ions.

“…In particular, the RE doped tungsten-tellurite glasses have been shown to have excellent properties for applications such as planar waveguides [10,11], amplifiers [12], lasers [4,5], single mode fiber lasers [13,14], and second harmonic generation devices [15]. However, tungsten-tellurite glasses have larger amounts of water when melted in air.…”

In this work, we investigate the spectroscopy properties of neodymium doped tungsten-tellurite glasses prepared in ambient and O 2-rich atmospheres. A conversion of TeO 4 to TeO 3 units was caused by the addition of Nd 3 þ into the glass, which was confirmed by absorption spectra and by Judd-Ofelt parameter behavior. The relaxation of the 4 F 3/2 level is dominated by radiative decay and cross-relaxation between Nd 3 þ and Nd 3 þ ions. The energy transfer from Nd 3 þ to the hydroxyl group is negligible when compared to the cross-relaxation. The luminescence quantum efficiency values of the 4 F 3/2 level decreases as the Nd 3 þ concentration increases, independently if determined by the Judd-Ofelt method or by the thermal lens technique. The observed reduction in the IR absorption associated to OH groups was not effective to improve the luminescence quantum efficiency.

“…In particular, tungsten-tellurite glasses have higher phonon energy and a higher glass transition temperature compared to the other tellurite glasses; therefore, they can be used at high optical intensities without exposure to thermal damage 3 . The RE-doped tungsten-tellurite glasses have been shown to have excellent properties for applications such as planar waveguides 4 , amplifiers 5 , and lasers 6,7 . Several RE ions have been studied for laser application.…”
