%X The synthesis of the thenoyltrifluoroacetone compound doped with terbium, dysprosium and europium encapsulated in a silica matrix (TTA:Tb:Dy:Eu@SiO<sub>2</sub>) were performed by the sol-gel method. The precursors to obtain the vitreous phase (SiO<sub>2</sub>) were: Tetraethylorthosilicate (TEOS, C<sub>8</sub>H<sub>2</sub>O<sub>4</sub>Si, 98%, Aldrich), and ethyl alcohol (CH<sub>3</sub>CH<sub>2</sub>OH, 99.5%, Meyer), distilled water and 0.05 ml of hydrochloric acid (HCl, Meyer). The sample with molar ratio 20:80 TTA:Tb:Dy:Eu@SiO<sub>2</sub> has the best emission intensity. Thermogravimetric analysis (TGA) shown that silica encapsulated samples decompose at lower temperatures than pure TTA:Tb:Dy:Eu luminescent material. Fourier Transform Infrared (IR-TF) shown the characteristic Si-O-Si bands that are presented at a wavelength of 1049, 853 and 440 cm<sup><span style=\"color:#4F4F4F;font-family:-apple-system, &quot;font-size:16px;white-space:normal;background-color:#FFFFFF;\">&amp;#45</span>1</sup> confirming that the luminescent material is encapsulated in a silica matrix, finally X-ray diffraction (XRD) shown that TTA:Tb:Dy:Eu@SiO2 composite is amorphous.
