Abstract: Department of Chemistry, GITAM University, Visakhapatnam-530 045, Andhra Pradesh, India E-mail : [email protected] Fax : 91-891-2790032 Department of Chemistry, National Tsing Hua University, Hsinchu 30013, Taiwan Manuscript received online 13 February 2015, accepted 19 May 2015 Gd3+ doped fluorapatite (FAp) had been prepared hydrothermally at 160 ºC in presence of an additive, 1,2,3,4-butanetetracarboxylic acid (BTCA). Morphology, phase and photoluminescence properties of samples were characterized by powder X-ray diffraction, FT-IR, SEM and fluorescence spectroscopy. Polycrystalline FAp : Gd3+ powder transformed to rod shaped crystals with influence of BTCA. After photoexcitation at 260 nm, FAp : Gd3+ emited ultraviolet emissions at 357 nm and 395 nm. Photoluminescent intensity of FAp : Gd3+ diminished with increasing concentration of BTCA.
