Abstract
Light emitting LEDs devices comprised of LED chips that emit light at a first wavelength, and a tinted thin film layer over the LED chip that changes the color of the emitted light. For example, a blue-light emitting LED chip can be used to produce white light. The tinted thin film layer beneficially consists of ZnSe, CeO , Al O , or Y O :Ce that is deposited using a chemical vapor deposition process, such as metal organic chemical vapor deposition (MOCVD), atomic layer chemical vapor deposition (ALD), plasma enhanced MOCVD, plasma enhanced ALD, and/or photo enhanced CVD. Suitable CVD precursors include Alkoxide, &bgr;-dikeonate, Metalloscene, Alkys, DMZn, DEZe, H Se, DMSe, TbuSe, and DESe.
