“…There was no significant change in the transmission range before and after corrosion. The primary transmission band falls between 275 nm and 360 nm with strong blocking ability exhibited at 200 nm–275 nm and 360 nm–650 nm due primarily to doping two transition metal ions Co and Ni [ [11] , [12] , [13] ]. When the Co 2+ ion is present as a [CoO 4 ], it will have a strong absorption of light near 600 nm, and when it is present as a [CoO 6 ], it will have a strong absorption of light near 500 nm.…”

In the present investigation, the crystallization kinetics of a glass with a molar composition 25Na 2 O-25ZnO-50P 2 O 5 (NZPO) is studied by means of a non-isothermal differential thermal analysis (DTA) and X-ray diffraction (XRD) techniques. XRD pattern of the as-synthesized glass indicates an amorphous glassy structure without additional crystalline phase. Moreover, the heat-treated glass sample shows the crystallization of the Na 2 ZnP 2 O 7 crystalline phase. The glass transition peak temperature increases with increasing heating rates and is ranged from 505.3 to 601.6 K. The crystallization shows the same behavior and the obtained values are ranged from 685.2 to 731.2 K. The activation energies for glass transition and crystallization are determined using different approaches and are in the range of 25.9-30.5 and 82.8-112.0 kJ mol −1 , respectively. The n and m kinetic parameters are each close to 3.0, which indicates bulk nucleation process with 3D growth of crystals.

“…The multiple oxidation states of the transition metal ions TMIs rich the glasses networks by many optical, electrical, and magnetic properties 1 – 3 . Optically, the TMIs give various specular colors to the glass networks, making them have a high optical absorption ability in the different regions of the electromagnetic spectrum such as UV, visible, and IR regions 4 – 6 . From the photoluminescence point of view, TMIs generate broad emission bands that have an adjustable wavelength and appropriate quantum yield 7 , 8 .…”

“…In addition, the Cu 2+ ion form a broad absorption band in the visible-near infrared range that usually arises due to the octahedral coordination of Cu 2+ , while the cuprous (monovalent copper) ion Cu + has a distinct absorption band in the UV region. These absorption bands are usually used to detect the presence of Cu + and Cu 2+ within the glass network 1 , 3 , 4 , 7 . Rare earth ions RE 3+ possess unique properties, the foremost of which is the property of photoluminescence, which made them dominant in many photonics and optoelectronics applications 17 , 18 .…”

A host glass network of 70B2O3–10Pb3O4–18ZnO–2Er2O3 (ErCoCu1) was proposed and the impact of 1 mol% of Co or/and Cu ions on its structural, thermal, optical, and green emission properties was studied extensively. The X-ray diffraction spectra confirmed the amorphous structure of the produced glasses. Density and density-based parameters behavior showed that the Co or/and Cu ions fill the interstitial positions of the proposed ErCoCu1 network, causing its compactness. Both ATR-FTIR and Raman Spectra affirmed the formation of the fundamental structural units of the borate network, B–O–B linkage, BO3, and BO4. Additionally, the penetration of Co or/and Cu ions inside the ErCoCu1 converts the tetrahedral BO4 units to triangle BO3 causing its richness by non-bridging oxygens. The addition of Co or/and Cu reduces the glass transition temperature as a result of the conversion of the BO4 to BO3 units. Optical absorption spectra for the host glass ErCoCu1 showed many of the distinguished absorption bands of the Er3+ ion. Penetration of Co ion generates two broadbands referring to the presence of Co2+ ions in both tetrahedral and octahedral coordination and Co3+ ions in the tetrahedral coordination. In the Cu-doped glasses, the characteristic absorption bands of Cu2+ and Cu+ were observed. A green emission was generated from the ErCoCu1 glass under 380 nm excitation wavelength. Moreover, no significant effect of Co or/and Cu on the emission spectra was recorded. The considered glasses had appropriate properties qualifying them for optoelectronics and nonlinear optics applications.
