Color-converted remote phosphor prototype of multiwavelength excitable borosilicate glass for white light-emitting diodes

doi:10.1088/1674-1056/21/9/098504

Abstract We report a unique red light-emitting Eu-doped borosilicate glass to convert color for warm white light-emitting diodes. This glass can be excited by from 394 nm-peaked near ultraviolet light, 466 nm-peaked blue light, to 534 nm-peaked green light to emit desired red light with an excellent transmission in the wavelength range of 400-700 nm which makes this glass suitable for the color conversion without great cost of luminous power loss. In particular, assembling this glass to commercial white light-emitting diodes, the tested results show that the color rendering index is improved to 84 with a loss of luminous power by 12 percent at average, making this variety of glass promising for inorganic "remote-phosphor" color conversion.

Keywords: white light-emitting diodes (WLEDs) color rendering index remote phosphor borosilicate glass
