| titleOfInvention | A kind of method improving LED encapsulation fluorescent material settling property |
| abstract | The invention provides a kind of method improving LED encapsulation fluorescent material settling property.The method mainly comprise the steps that (1) by fluorescent material ultrasonic disperse in hydrous ethanol solution, drip ammonia, regulate pH value, obtain suspension；(2) mixed liquor of tetraethyl orthosilicate, ethanol is instilled suspension, fully after reaction, washing, dried, obtain SiO 2 The fluorescent material of cladding；(3) by SiO 2 Cladding fluorescent material, coupling agent and dry toluene mixing post-heating reaction, washing, dried obtain modified fluorescent material.The present invention, mainly by being modified phosphor surface, strengthens fluorescent material and LED encapsulation silica gel or the compatibility of epoxy resin and interaction force, improves the fluorescent material compatibility in packaging plastic and sedimentation stability, improves homogeneity of product. |
