Near-infrared photoluminescence enhancement and radiative energy transfer in RE-doped zinc-silicate glass (RE = Ho, Er, Tm) after silver ion exchange

Influences of copper–potassium ion exchange process on the optical bandgaps and spectroscopic properties of Cr3+/Yb3+ co-doped in lanthanum aluminosilicate glasses

“…3,12,19 In fact, the ion exchange process between coinage ions and alkali ions has many advantages compared with other traditional methods. 21 For example, in many previous researches [22][23][24] as well as in our recent work, 25 it was shown that the coinage ions introduced by the ion exchange processes could signicantly affect the optical properties of the glasses such as the refractive index, the optical density, the nearinfrared emission spectrum, or even chemically strengthen the glasses 26,27 as well as modify glass structure. 28 Through the ion exchange process, the Cu + and Cu 2+ ions, as well as Ag + ions, could be ejected into the surfaces of the glasses, 22,24,[29][30][31][32] then become neutral copper or/and silver atoms and grow into copper or/and silver nanoparticles (CuNPs or/and AgNPs).…”

Active and Quantum Integrated Photonic Elements by Ion Exchange in Glass

“…A broad review on Er-Yb laser and amplifiers, covering both the photoluminescence issues and the various materials and technologies, was published in 2011 by Bradley and Pollnau [180]. In the last years, owing to the fact that Er-Yb co-doped ion-exchanged waveguides and devices in silicate and phosphate glasses constitute a mature technology, only very few papers have been published, including some ones related to up-down frequency conversion with application to lighting and solar cells [164,[181][182][183][184]. The main research focus has been shifted toward technological platforms that could allow integration with silicon and compatibility with CMOS technology; thus, rare-earth doped aluminum oxide has emerged as a new excellent material.…”
