A novel white-light phosphor GdVO<SUB>4</SUB>:Ho<SUP>3+</SUP> was prepared via a simple hydrothermal reaction route. Under ultraviolet excitation, the as-prepared nanocrystals showed a broad band emission and sharp lines, which are associated with the oxygen vacancies around V<SUP>4+</SUP> ions and the typical f–f transitions of Ho<SUP>3+</SUP> ions, respectively. The coexistence of broad emission and sharp lines results in the bright white light with a quantum yield of 28%.
