DOWNCONVERSION FILM ELEMENT |
摘要 |
A downconversion film element comprises quantum dots and phosphor, wherein either (a) the quantum dots emit a peak red wavelength in a range from 615 to 660 nm and a FWHM of less than 50 nm, and the phosphor emits a peak green wavelength in a range from 515 to 555 nm and a FWHM of less than 80 nm and has an internal fluorescence quantum yield of 75% or greater or (b) the quantum dots emit a peak green wavelength in a range from 515 to 555 nm and a FWHM of less than 40 nm, and the phosphor emits a peak red wavelength in a range from 615 to 645 nm and a FWHM of less than 80 nm and has an internal fluorescence quantum yield of 75% or greater. |
