| Abstract: | Pure lanthanum titanate doped with europium metal ions (La 2 Ti 2 O 7 :Eu 3+ ) and dispersed in silica matrix phosphor powder was prepared by sol–gel process followed by thermal treatment. The prepared nanophosphors were characterized by powder X-ray Diffraction (XRD), Fourier Transform Infrared (FT-IR), Transmission Electron Microscope (TEM), Energy Dispersive Spectroscopy (EDX), and Photoluminescence Spectroscopy (PL). The effects of silica, thermal treatment, Eu 3+ ion, and surfactant (CTAB) concentrations on the crystal, morphology, and photoluminescence properties were investigated. The present work found that dispersion of La 2 Ti 2 O 7 :Eu 3+ into silica matrix significantly altered the morphology of La 2 Ti 2 O 7 :Eu 3+ from high crystalline micro-plate like shape into amorphous aggregated Nano-spherical shape. The high separated spherical shape with intense red PL emission and long lifetime was obtained from 10 mol% Eu 3+ :La 2 Ti 2 O 7 :Eu 3+ , dispersed into silica matrix, and prepared in the presence of CTAB. The high PL Nano-phosphor has been successfully used in developing latent fingerprint from various forensic relevant materials. [ABSTRACT FROM AUTHOR] |
