In the present work, nanocrystalline Ca3Y2(1−x)Si3O12:Eux (x=1, 5, 10, and 20 mol%) novel phosphors were synthesized by a sol–gel method. The effect of temperature and concentration on structural and luminescence properties of nanocrystalline powders were investigated under UV excitation. The X‐ray diffraction profiles showed that all peaks could be attributed to the orthorhombic Ca3Y2Si3O12 doped Eu phase at the various calcination temperatures with various concentrations. Scanning electron microscopy was carried out to understand the surface morphological features and grain sizes. Photoluminescence (PL) measurements exhibited the presence of all transitions of Eu3+ dopant, being the 5D0→7F2 transition the most intense under the charge transfer band and it was observed to be located at around 250 nm. It was also found that, the PL intensity was strongly dependent on both the calcination temperature and dopant concentration. The highest PL intensity was observed for x=5 mol% with temperature at 1000°C. It was observed that the spectral features possess sharp and bright emission for potential applications on the flat panel displays and some other related electronic systems, in observing the images of red color.
