“…Since there is are no detectable CsCaCl 3 PNCs in the PG and the one heat-treated at 520 1C, the blue emission is considered to arise from 5d -4f transitions of Eu 2+ ions in the glass matrix, which are reduced during glass melting. 37,38 However, with a further increase in the heat-treatment temperature, emission from Eu 3+ ions is significantly reduced, and blue emission dominates the whole emission spectra without any further shift in the peak wavelength (Fig. 3(d)).…”

“…It is clear that the remarkable red shift results are observed from 434 (Si‐20) to 455 nm (Si‐45) and 434 (Eu‐0.075) to 471 nm (Eu‐1.6) in both Si‐x and Eu‐y glass samples, respectively. The degree of ionization increases with increasing concentration of Eu 2+ ions, which may decrease the 4f 6 5d energy level, resulting in red shifting of the emission peak 24 …”

At present, doping of different alkaline‐earth metal ions is mainly used to tune the emission peak of europium (Eu) ions in glasses. However, the optimization of Eu‐doped glasses is hindered due to limited discussion on the relationship between local glass network structure, concentration of Eu ion dopants, and visible light emission by Eu ions. In this study, we prepared two series of borosilicate glasses doped with Eu ions, by varying the ratio of SiO2 to B2O3 and adjusting the concentration of Eu ion dopants to obtain cyan emission. The optical properties, structure, and differential scanning calorimetry (DSC) of the investigated glasses were systematically studied. With gradual increase in the content of SiO2, red shifting from 471 nm to 492 nm was observed under excitation at 410 nm, with the introduction of Eu2O3 also causing a redshift from 471 nm to 488 nm. The spectral results also revealed that under excitation at 410 nm all the glass samples exhibited cyan emission, with the optimal cyan peak at 492 nm (Si‐45) and the strongest cyan emission at Eu‐0.4 (480 nm). By adjusting the concentration ratios of Si to B in europium‐doped borosilicate glass, it was observed that by altering the [SiO4] tetrahedra, [BO4] tetrahedra, and [BO3] triangles within the glass ultimately cyan emission can be achieved. By varying the doping concentration of Eu ion to change the degree of local Eu ion clustering in the glass system, cyan emission can be achieved by tuning the emission peak.

“…Since the absorption band around 350 nm was also confirmed with previous reports on the Eu-doped glasses, the origin was considered be the 4f-5d transitions of Eu 2+ . (38,43,44) Figure 3 shows PL excitation and emission maps of 0.1% Eu-doped 20CsBr-20BaBr 2 -60ZnBr 2 glass as a representative. Under excitation wavelengths of 280-380 nm, the emission band was observed at around 415 nm.…”

20CsBr-20BaBr 2 -60ZnBr 2 glasses doped with various concentrations of Eu (0.01, 0.05, 0.1, and 0.5%) were synthesized by the melt-quenching method, and their optical and scintillation properties were investigated. In the photoluminescence (PL) and X-ray-induced scintillation spectra of all the prepared glasses, the emission band around 415 nm due to the 5d-4f transitions of Eu 2+ was observed. In the scintillation spectrum, the 0.5% Eu-doped glass showed sharp emission peaks at 590 and 610 nm, which have a typical spectral shape for the 4f-4f transitions of Eu 3+ . Under 241 Am α-ray irradiation, the light yields of 0.01 and 0.05% Eu-doped glasses were 75 and 100 ph/5.5 MeV-α, respectively.
