Abstract

The effect of the viscosity of phosphor slurry prepared by mixing two types of silicone resins with different viscosities in various ratios on the properties of pre-formed phosphor films was investigated. The pre-formed phosphor films manufactured using these phosphor slurries were evaluated for curing characteristics, breaking strength, shear strength, and optical properties. The test results demonstrated that increasing the amount of high-viscosity silicone resin in the composite resin resulted in decreased curing reaction rate, decreased breaking strength, and correlated color temperature, whereas the viscosity and adhesion strength of the composite resin increased. Among seven different mixing ratios of the low- and high-viscosity silicone resins prepared for the composite resin, white-light emission was realized for the ratio 70:30, and the pre-formed phosphor film with this ratio exhibited high breaking strength and low adhesion strength. The breaking strength thus obtained was 24.0 MPa, the adhesion strength was 0.17 MPa, the color temperature was 5,650 K, and the two chromaticity coordinates (CIE(x, y) (1931)) were (0.3293, 0.3251).
