A luminescence compound is provided to show significantly improved luminous efficiency. An organic light emitting diode using the same compound as an emission layer is provided to show excellent luminescent properties such as high external quantum efficiency, brightness and low driving voltage. An iridium complex compound is represented by a formula(1), wherein each L1, L2, R1 and R3 is H, and each L3 and R2 is a group represented by a formula(2) of -SiD1D2D3(wherein each D1 to D3 is methyl). In a method for preparing an organic light emitting diode(OLED) by forming an anode electrode, an emission layer and a cathode electrode on a substrate in sequence, the emission layer is formed by preparing CBP(cAMP-responsive Element Binding Protein) as a host material and depositing the iridium complex compound of the formula(1), wherein each L3 and R2 is trimethylsilane, and each L1, L2, R1 and R3 is H, as a dopant.
