An ultraviolet-excited phosphor is composed of a dysprosium and thulium-activated rare-earth aluminum, scandium borate that is represented by a general formula (Y1-x-yTmxDyy)Al3-zScz(BO3)4 (where 0 < (x+y) & 1, 0 & z & 3). This phosphor, when irradiated by ultraviolet light having a wavelength of 350 nm or less, can produce white light having composed of the wavelengths 451, 455, 470, 474, 481, 485, 564, 567, 571, 574, 579 and several peaks in the range of Ò5 nm around these wavelengths with higher efficiency and stronger emitted intensity, having a colour temperature of approximately 4600 - 10000 K.
