摘要：

We suggest a simple way of forming a nonconventional remote phosphor layer for white light-emitting diodes. A printing technology using a paste consisting of yellow (Ba,Sr,Ca)(2)SiO4:Eu2+ silicate phosphor and ultraviolet (UV)-curable polymer is applied to form solid planar films on a common soda lime silicate glass substrate through UV radiation. Relative content of the phosphor was adjusted for the best dispersion of the phosphor particles in the polymer matrix with better emission and luminescence performance. As a result, the 70 wt. % phosphor-embedded film has a luminous efficacy of similar to 70.1 lm/W at 200 mA. (C) 2015 Optical Society of America
