Abstract

One-step synthetic route has been developed for the preparation of Nd(OH)₃ nanorods in the presence of n-butylamine. The as-prepared sample is in hexagonal phase with good crystallinity, and made up of highly dispersed nanorods of 14–15 nm in diameter and up to 40–50 nm in length at 120°C for 24 h. Optical measurements show that these nanorods have intensive photoluminescence (PL) at room temperature and have the potential to become optical materials. Thermogravimetric analysis (TGA) of the Nd(OH)₃ nanorods reveals that the nanorods remain stable up to 220°C and decompose to the derived oxide of Nd₂O₃ at higher temperatures. The derived oxides show the promise active catalyst for the oxidation of carbon monoxide. In addition, this synthetic route has been developed for the synthesis of a series of other lanthanide hydroxides nanorods including Pr(OH)₃, Sm(OH)₃, Eu(OH)₃, Gd(OH)₃, Tb(OH)₃ and Dy(OH)₃, and their PL properties, thermostability and catalytic properties are investigated.
