Frequency upconversion emissions in layered lead–germanate–tellurite glasses for three-color display

Influence of Cr3+ on yellowish‐green UC emission and energy transfer of Er3+/Cr3+/Yb3+ tri‐doped zinc silicate glasses

“…In recent years, the upconversion (UC) emission of rare‐earth (RE 3+ ) co‐doped in the glass/glass‐ceramics materials continues to be extensively studied by their potential applications in many fields such as biomedical imaging, three‐dimensional color display, 1,2 optical thermometry, 3 temperature sensors, 4 solar cells, 5 and biomarkers 6 . There have been many studies aiming to enhance UC emission of some typical RE 3+ ions due to their different applications.…”

Multiple visible emissions by means of up-conversion process in a microstructured tellurite glass optical fiber

“…Indeed the possibility for one glass to host several Yb 3+ /A pairs appears appealing. However, as discussed in [17], the presence of several RE ions in the same glass matrix leads to detrimental energy transfer phenomena. These interactions quench the visible emissions of each acceptor ion and reduce the efficiency of the overall up-conversion process.…”

“…To overcome this issue, Yang et al [17] suggested to separate spatially emitting ions by a layered structure where each layer embeds one Yb 3+ /A pair. Also beneficial for up-conversion process is the tight optical confinement provided by waveguide structures.…”

Yb^3+, Tm^3+ and Ho^3+ triply-doped tellurite core-cladding optical fiber for white light generation

“…More recently, great attention has been paid to generating white light from solid-state materials by controlling the intensities of each RGB emissions [8,9]. Er 3+ , Tm 3+ and Yb 3+ ions were used but it has been difficult to simulate the white light due to the quenching of up-converted emission [10]. Also, white light generation has been obtained in a photonic crystal fiber that is triply filled with dye solutions [11].…”
