Luminescence characterizations of YAG:Ce crystal via sol-gel method for radiotherapy

Sol-gel assisted molten-salt synthesis of novel single phase Y3–2xCa2xTaxAl5−xO12:1%Eu garnet structure phosphors

“…However, as the precursor for such reactions the mixture of powders is regularly used. To the best of our knowledge, there is no reported cases in literature that these two methods were combined [9,10].…”

Dosimeter Based on YAG: Ce Phosphor via Sol-Gel Method for Online X-ray Radiation Monitoring

“…In previous studies [26,27], it was found that sintering samples under nitrogen atmosphere obtains better results, so a nitrogen atmosphere was selected when the samples in this paper were prepared. At the same time, the XRD spectrum of samples sintered at different temperatures showed a slight difference, as shown in Figure 3.…”

“…where β is the FWHM of the selected peak, θ is the Bragg angle, λ is the wavelength of X-rays, k is the constant (when β represents FWHM, k takes 0.89), and D is the sample grain size of the sample [27][28][29]. Table 2 shows the estimated grain size of YAG: Ce powder synthesized by the sol-gel method; the grain size is relatively small, ranging from 57 to 73 nm, and the sample of 1400 • C has the smallest grain size, making it easier to evenly distribute, forming a stabler lattice structure, and contributing to better optical characteristics among the samples.…”

“…Meanwhile, the sol-gel method is more friendly and simpler to generate solid metal oxides with even better chemical uniformity. The doping concentration and sintering atmosphere determine the materialized properties of the powder to a great extent, and in earlier work, we studied the luminescence and radiation characteristics of the powder material by the coprecipitation method [26] and sol-gel method [27], respectively.…”
