Abstract

In this study

on the base of literatures and traditional method of chemical precipitation process

we optimized the conditions of the experimental and prepared the lanthanide complexes of Tb(Sal)

·3H

Onanocrystallines with different sizes by the ammonia gas

a series of different proportion ammonia(1:1～1:16) and different pH buffer solution.In order to compare

the complex Tb(Sal)

·2H

O were obtained by the traditional chemical precipitation method.Using the elemental analysis

infrared spectrum

TGA-DSC

TEM and SEM

we confirmed that the construction

thermal properties and size of Tb(Sal)

·3H

O nanocrystalline and Tb(Sal)

·2H

O complex.In addition

fluorescence excitation and emission spectrum

ultraviolet absorption spectrums and the energy transfer process between the organic ligand and center terbium ions were investigated.Our results indicated that the sizes of the nanocrystalline of Tb(Sal)

·3H

O particle were in the range from 50 to 250 nm

the size of Tb(Sal)

·3H

O nanocrystallines was minimal and well-proportioned by the ammonia gas proportion 1:16

these nanocrystallines also exhibited terbium ion characteristic luminescence

the luminescence intensity of Tb(Sal)

·3H

O nanocrystallines prepared with the proportion 1:16 ammonia is the strongest.However

the size of the complex Tb(Sal)

·2H

O were 0.3～0.7 μm.These results of terbium complex Tb(Sal)

·3H

O nanocrystallins can provide a basis for further expanding its application in luminescent materials and magnetic materials.
