A strong blue emission is observed for hybrid Ce 3+ /Ce 4+ cerium phosphate nanotubes, whereas Ce 3+ phosphate nanowires exhibit a characteristic double‐peak UV luminescence (see picture). These cerium phosphate systems were obtained by annealing novel cerium( IV ) phosphate nanotubes at different temperatures.
