Controlled synthesis of tetragonal terbium orthophosphate nanostructures through a solvothermal route

Abstract

The tetragonal TbPO 4 was controlled synthesized via a simple solvothermal route by using glycol as solvent. The structures and micromorphologies of the as-synthesized TbPO 4 have been investigated by means of X-ray powder diffraction (XRD) and field-emission scanning electronic microscopy (FE-SEM). The results showed that the tetragonal TbPO 4 are composed of square-like particles about 200 nm in diameter. The photoluminescence spectra exhibited that the emission spectra of the sample could be divided into two parts, representing the 5 D 4 ? 7 F J (J = 6, 5, 4, 3) transitions and 5 D 3 ? 7 F J (J = 6, 5, 4, 3) transitions of Tb 3? .

Folic Acid-Conjugated Silica-Modified TbPO4·H2O Nanorods for Biomedical Applications

“…Rare earth containing luminescent nanophosphors with many advantages such as high stability, strong luminescence, noncomplex fabrication, easy surface functionalization, and friendly to environment and human body have been very promising materials for healthcare application, especially for biomedical fluorescence labeling [1][2][3][4][5][6][7][8][9][10]. Recently, the development of rare earth containing luminescent nanorods for application in biomedicine is attracted topic for scientists in materials science field [11][12][13][14][15].…”

A Facile Synthesis and Optical Properties of Bundle-Shaped TbPO4·H2O Nanorods

“…In recent years, inorganic nanostructures with well-defined shapes and sizes have attracted growing attention because of their unique size-and shape-dependent properties [1][2][3]. Among many kinds of nanostructured materials, lanthanide orthophosphates (LnPO 4 ) with uniform size and various morphologies have been prepared by some mild and controllable methods [4,5] and attracted great interest because of their unique properties including very low solubility in water (The solubility product constant, K sol = 25-27) [6], high thermal stability, high index of refraction, and high luminescent efficiency [7,8]. These materials have been used as active components in a wide range of applications such as phosphors, laser hosts, and biolabeling [9][10][11][12].…”
