权利人:PENN STATE RES FOUND
摘要:A method of microwave synthesis of phosphors includes a microwave furnace having a microwave chamber; providing starting material in the microwave chamber; and subjecting the starting material to microwaves, whereby the starting material is synthesized into phosphors. An insulation package for use in microwave synthesis is disclosed that includes an insulator having an opening therein, wherein the opening is substantially symmetrically disposed in relation to a central axis of the insulator, and wherein the opening is adapted to receive starting material. A susceptor configuration may be positioned within the cavity, wherein the insulator, the cavity, and the susceptor configuration are substantially symmetrically disposed in relation to an axis of rotation of the insulation package. A microwave furnace for continuous microwave synthesis of phosphors is also disclosed.

摘要:A UV-VIS light emitting system is described. The system comprises a phosphor mixture emitting within the UVB and the visible range of the electromagnetic spectrum. The system has an efficiency of 84 lm/W or larger and a spectral power distribution E (λ) such that the ratio Ǫ between the dose rate for vitamin D synthesis R n D = ∫ E {λ) A n D (λ) d λ and the luminous flux Φ = ∫ E {λ) V (λ) d λ is 10 -6 J/m 2 lms or larger. The UV-VIS light emitting system is therefore suitable for general lighting applications while providing controlled stimulation of vitamin D synthesis.
