Abstract

In this report, the thermal analysis of Tris (8-hydroxyquinoline) aluminum (Alq3) is presented. The thermal conductivity of Alq3, in a temperature range between 300 and 523 K, was determined by measuring its thermal diffusivity and specific heat. The thermal diffusivity measured by the laser flash method is found to decrease with temperature. The specific heat increases with temperature without any trend of saturation until the highest temperature (573 K) was investigated. The room temperature specific heat of Alq3 is about 1.03 J/g per K and the value at 523 K is about 1.67 J/g per K. A very low thermal conductivity (room temperature) of Alq3, 0.107 W/m per K, was determined. The thermal conductivity is found to increase with temperature within the investigated temperature range. The measured thermal conductivity was applied to the modeling of a heat spreading during a device operation.
