摘要： A luminescent cerium (Ce) doped compound emitting bright red light, comprising a calcium silicate nitride ternary system, such as CaSiN2δOδ: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 Pr3+, or any combination thereof, with or without Tb3+as a co-dopant, has the general formula: Bix,Ln1-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.

摘要： Three new cerium (Ce) based phosphor materials based on nitride and oxy-nitride compounds emit yellow or blue to green photons upon excitation by ultraviolet (UV) or blue light radiation. The two yellow emitting compounds belong to the quartenary Ca—Al—Si—N system with distinct structures. These bright yellow phosphors can be used for white light applications by combining either a blue light emitting diode (LED) and a yellow phosphor, a blue LED and green-orange phosphors, or an ultraviolet (UV) LED with three phosphors, i.e., red, blue and green (RGB) phosphors. The bright blue-green phosphor, which may be described by Sr2SiO4-δNδ, can be used in the UV LED plus 3 RGB phosphors setup.
