Abstract
The first upconversion luminescence in a 5d electron system is reporte d. At temperatures below 100 K excitation of Cs2ZrCl6:Os4+ in the NIR at 11226 cm(-1) leads to VIS and NIR luminescences between 17000 and 1 1500 cm(-1). The intraconfigurational character within (t(2g))(4) of t he d-d transitions involved is thought to be mainly responsible for th is unusual phenomenon in a 5d transition metal complex.
