【 摘 要 】

The structural, and optical properties of the Eu3+ ion in alumino-silicate 35Al(NO3)3: (65-x) SiO2 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 Eu3+ concentrations are recorded with excitation wavelength 370 nmhave been recorded atroom temperature (RT). The PL spectra showed the (5D0→7FJ; J = 0...., 4) transitions of Eu3+ in the prepared glasses. The rise in Eu3+ 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.
