Abstract
- New copper-containing borates with the general formula PbCd<subscript>2–x</subscript>B<subscript>6</subscript>O<subscript>12</subscript>:xCu<superscript>2+</superscript> have been prepared by solid-state reactions and characterized by X-ray diffraction and IR spectroscopy. A continuous series of substitutional solid solutions isostructural with monoclinic PbCd<subscript>2</subscript>B<subscript>6</subscript>O<subscript>12</subscript> (sp. gr. P2<subscript>1</subscript>/n) has been shown to exist in the range 0 < x ≤ 0.08. Replacing cadmium atoms by copper atoms, which are smaller in size, leads to a linear decrease in unit-cell parameters across the solid solution series. The IR spectroscopy and X-ray diffraction data suggest the presence of BO<subscript>3</subscript> and BO<subscript>4</subscript> anions in the structure of the borates. The thermoluminescence intensity has been measured as a function of activator content in the range 25–400°C. The thermoluminescence intensity in the borates increases with activator content, reaching a maximum at x = 0.06, and decreases at higher doping levels. The powder borates studied here can be used as a key component of new luminescence materials. [ABSTRACT FROM AUTHOR]
