Abstract

Abstract: Thin films of Ca1-xSrxS:Eu with tunable photoluminescence are fabricated by cathodic magnetron-assisted co-sputtering. Broad and intense luminescence has been observed, and its color shifts progressively from yellow to dark red by changing thin film composition. One promising application of these thin films is for improving the color rendering index of YAG:Ce-coated blue LEDs up to 93. Still broader emission is expected by creating a continuous composition gradient which can be realized by adjusting the power ratio applied on the two targets during the film deposition.

Emission spectra of the thin films excited by 467-nm blue light. (a) Luminescence of the as-deposited and heat treated Sr6Ca0 thin films. (b) Normalized emission bands of the series of thin films after annealing, showing a continuous shift. The inserted photos shows the color change of the photoluminescence of the thin films. A 495-nm high-pass filter was used during the record of the photos in order to remove the incident blue light. The inserted curve presents the variation of the FWHM of the emission bands of the thin films and of the powders reported in [12].
