    摘要: A luminescent cerium (Ce) doped compound emitting bright red light, comprising a calcium silicate nitride ternary system, such as CaSiN2-δOδ:Ce3+, that crystallizes in a face-centered cubic unit cell with a lattice parameter of ˜a=14.88 Å. The Ce doped compound can be used for white light applications either: (i) to enhance the light quality of the system based on a blue LED with a yellow or green phosphor, (ii) as an orange phosphor in combination with a blue LED and a green phosphor, or (iii) as a red phosphor in a setup comprising a ultraviolet (UV) LED and red, green and blue (RGB) phosphors. Substitution of smaller elements on the Ca site or larger elements on the Si site leads to a decrease of the emission wavelength towards the yellow or orange region.

    摘要: A red phosphor composition in combination with a semiconductor light emitting device (e.g., VCSEL, LED, or LD), preferably a GaN based device, that emits light at a bright violet-blue light range, i.e., having a wavelength in the range of 400 nm to 600 nm, which can be further combined with green and blue phosphors. The red phosphor composition in the combination is a vanadate combined with yttrium, gadolinium and/or lanthanum and activated with trivalent Eu3+, Sm3+ and Pr330 , or any combination thereof, with or without Tb3+ as a co-dopant, has the general formula: BixLn1-xVO4:A where x=0 to 1, Ln is an element selected from the group consisting of Y, La and Gd, and A is an activator selected from Eu3+, Sm3+ and Pr3+, or any combination thereof, with or without Tb3+ as a co-dopant. Novel red phosphor compositions are provided when x is greater than 0 and less than 1, preferably 0.05 to 0.5.
