摘要
There is provided a white light illumination system. The illumination system includes a radiation source which emits either ultra-violet (UV) or x-ray radiation. The illumination system also includes a luminescent material which absorbs the UV or x-ray radiation and emits the white light. The luminescent material has composition A2-2xNa1xExD2V3O12. A may be calcium, barium, strontium, or combinations of these three elements. E may be europium, dysprosium, samarium, thulium, or erbium, or combinations thereof. D may be magnesium or zinc, or combinations thereof. The value of x ranges from 0.01 to 0.3, inclusive.
