Abstract
Present red phosphor converters provide spectra dominated by sharp lines and suffer from availability and stability issues which are not ideal for color mixing in display or solid state lighting applications. We examine the use of mono dispersed 3 nm silicon nanoparticles, with inhomogeneously broadened red luminescence as an effective substitute for red phosphors. We tested a 3-phase hybrid nanophosphor consisting of ZnS:Ag, ZnS:Cu,Au,Al, and nanoparticles. Correlated color temperature is examined under UV and LED pumping in the range 254, 365–400 nm. The temperature is found reasonably flat for the longer wavelengths and drops for the shorter wavelengths while the color rendering index increases. The photo stability of the phosphors relative to the silicon nanoparticles is recorded. The variation in the temperature is analyzed in terms of the strength of inter-band–gap transition and continuum band to band transitions.
