Abstract
Y2SiO5:Gd3+ phosphors have been prepared in an air-filled atmosphere at calcination temperatures of 1000 °C and 1250 °C, using the solid state reaction technique, the phosphors were synthesized in different concentrations. FTIR techniques were used to analyze the produced phosphors and Using X-ray diffraction (XRD), the monoclinic structure was identified. To examine the luminescence behavior of the synthesized phosphors, their photoluminescence spectra have been recorded. The material showed a band in the narrow band UV spectral regions at 315 nm (6P7/2
8S7/2), upon 275 nm excitation. Due to its tremendous spectrum brightness and narrow bandwidth, the UV emission of Gd3+ in Y2SiO5 at 315 nm is a suitable choice for a source of light in microelectronic photolithography. The material's Thermoluminescence (TL) was calculated using a UV exposure duration range of 5 to 25 min. The sample's peak temperature of 258 °C is well defined, exhibiting an excellent thermoluminescence dosimeter peak, as the sample is exposed to more UV radiation for longer periods of time, the intensity of the corresponding TL increases. The kinetic parameters were obtained using the peak-shape technique and the CGCD methodology. According to the findings, Gd3+ doped Y2SiO5 phosphors might be a useful light source for applications involving microelectronic photolithography.
