Summary, etc. <p>The structural, and optical properties of the Eu<sup>3+</sup> ion in alumino-silicate 35Al(NO<sub>3</sub>)<sub>3</sub>: (65-x) SiO<sub>2</sub> glass (x = 0.75, 2.0, and 4.0 mol%) were investigated. X-ray diffraction proved that the present glasses are amorphous. FTIR spectral analysis was used to determine which functional groups were present at specific annealing temperatures. The PL spectra with different Eu<sup>3+</sup> concentrations are recorded with excitation wavelength 370 nm have been recorded at room temperature (RT). The PL spectra showed the (<sup>5</sup>D<sub>0</sub>→<sup>7</sup>F<em><sub>J</sub></em>; <em>J </em>= 0...., 4) transitions of Eu<sup>3+ </sup>in the prepared glasses. The rise in Eu<sup>3+</sup> ions in the host matrix was the explanation for the concentration quenching behaviour that was also seen. To ensure the dominant emission of the present glasses, the PL spectra were characterized using the CIE 1931 chromaticity diagram, and the results were discussed and reported in detail.<em></em></p>
