“…Absorption peaks present at 620 and 700 cm −1 ascribed to the ZnO 4 asymmetric stretching and SiO torsional vibrations whereas peaks at 812 and 884 cm −1 were assigned to the SiO 4 symmetric stretching vibration [21,38,41,42,45,46]. The absorption peak around 989 cm −1 was assigned to the SiO 4 asymmetric stretching vibration [15,45,47]. The existence of the vibrations of SiO 4 and ZnO 4 groups being evidence of the formation of the Zn 2 SiO 4 phase [47][48][49].…”

“…The existence of the vibrations of SiO 4 and ZnO 4 groups being evidence of the formation of the Zn 2 SiO 4 phase [47][48][49]. The vibrational band observed at 1110 cm −1 ascribed to the Si-O-Si asymmetric stretching vibrations [15,20]. From the Figures 3 and 4, it is found that the increment in the absorption peak intensity at 580 cm −1 which implied the enhancement of ZnO 4 group unit by replacing the Si atoms [48].…”

“…These numerous interests in zinc silicate phosphor also due to their interesting properties, having 2 of 16 good thermal and chemical stability [9], excel in water resistance with better resistance to nuclear radiation [10]. Zinc silicate also exhibits excellent luminescence properties when homogenously grows with an inorganic oxide crystal [11][12][13][14][15].…”

This research paper proposes the usage of a simple thermal treatment method to synthesis the pure and Eu3+ doped ZnO/Zn2SiO4 based composites which undergo calcination process at different temperatures. The effect of calcination temperatures on the structural, morphological, and optical properties of ZnO/Zn2SiO4 based composites have been studied. The XRD analysis shows the existence of two major phases which are ZnO and Zn2SiO4 crystals and supported by the finding in the FT-IR. The FESEM micrograph further confirms the existence of both ZnO and Zn2SiO4 crystal phases, with progress in the calcination temperature around 700–800 °C which affects the existence of the necking-like shape particle. Absorption humps discovered through UV-Vis spectroscopy revealed that at the higher calcination temperature effects for higher absorption intensity while absorption bands can be seen at below 400 nm with dropping of absorption bands at 370–375 nm. Two types of band gap can be seen from the energy band gap analysis which occurs from ZnO crystal and Zn2SiO4 crystal progress. It is also discovered that for Eu3+ doped ZnO/Zn2SiO4 composites, the Zn2SiO4 crystal (5.11–4.71 eV) has a higher band gap compared to the ZnO crystal (3.271–4.07 eV). While, for the photoluminescence study, excited at 400 nm, the emission spectra of Eu3+ doped ZnO/Zn2SiO4 revealed higher emission intensity compared to pure ZnO/Zn2SiO4 with higher calcination temperature exhibit higher emission intensity at 615 nm with 700 °C being the optimum temperature. The emission spectra also show that the calcination temperature contributed to enhancing the emission intensity.

“…The presence of SiO 4 and ZnO 4 group vibrations [29] might indicate the creation of the Zn 2 SiO 4 phase. The Si-O-Si asymmetric stretching vibrations were ascribed to the vibrational band detected at 1100 cm −1 [30]. The non-existence of peaks in the region of 2000-3000 cm −1 indicates the lack of CO mode and C = H stretching modes of organic sources.…”

Synthesis of Eu3+-Doped ZnO/Zn2SiO4 Composite Phosphor for Potent Optoelectronic Applications

et al. 2021

Eu 3+ -doped Zn 2 SiO 4 /ZnO phosphor-based composites were prepared using a simple thermal treatment method. The effect of Eu 3+ content on the morphological and photoluminescence performance was examined using XRD, FTIR, FESEM, UV-Vis, and PL measurement. The existence of two crystal phases by the XRD measurement confirmed the development of zincite (ZnO) and zinc silicate (Zn 2 SiO 4 ) crystal phases. Besides, the FTIR spectra and FESEM micrograph support the XRD result by verifying ZnO and Zn 2 SiO 4 phase formation through the existence of their characteristic Zn-O-Si and Zn-O vibration modes with the decrement of SiO 4 broad absorption band as the Eu 3+ concentration increased. Also, UV-Vis absorption spectra presented by the composite samples displayed a broad absorbance that confirmed the addition of Eu 3+ ions in the ZnO/Zn 2 SiO 4 has caused the absorption edge of the curve having red shift. The photoluminescence spectrum showed red shift light emissions at 485 and 615 nm, associating with the Zn 2 SiO 4 crystal phase, in addition to the ZnO crystal phase. From the interesting results achieved, this ZnO/Zn 2 SiO 4 phosphor-based composite material can be a potent candidate in optoelectronic applications.
