Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) Processo FAPESP: 03/10195-1 This work reports the chemical etching effect of ethylenediaminetetraacetic acid (H(4)EDTA) on the particle size of Gd2O3:Nd3+ phosphor obtained from the thermal decomposition of Gd-2(OH)(2)(CO3)center dot nH(2)O:Nd3+. Thermogravimetric behavior of the precursor Gd-2(OH)(2)(CO3)center dot nH(2)O:Nd3+ (2 at%) is presented and discussed. Structural and spectroscopic investigation of the Gd2O3:Nd3+ powders revealed that this phosphor displays a band emission in the infrared region, which is an important feature for photonic applications. The treatment with different EDTA concentrations results in different Gd2O3:Nd3+ particle size. Through SEM analysis, we have demonstrated that the particle size of Gd2O3:Nd3+ decreases with increasing amount of EDTA. Hereby, we report a chemical etching method as a route to obtain particle size control which is an important requirement to improve phosphor properties and its applicability. (C) 2010 Elsevier B.V.
