Abstract: The present application relates to a transparent cured siloxane material having high transparency and refractive index, long-term heat resistance and ultraviolet resistance, and excellent hardness, and a preparing method using the same. The transparent cured siloxane material is prepared by using an oligosiloxane resin having a vinyl-silicon bond through a hydrolysis-condensation reaction, an oligosiloxane resin having a hydrogen-silicon bond through a hydrolysis-condensation reaction, and a metal catalyst for hydrosilylation. The present application also relates to a light emitting diode encapsulating material including the transparent cured siloxane material and a light emitting diode capsulated by using the light emitting diode encapsulating material.
