This work investigated the effect of temperature changes on the light output of LAB based liquid scintillator in a range from -5°C to 30°C with a-particles and electrons in a small scale setup. Assuming a linear behaviour, a combined negative temperature coefficient of (-0.29+-0.01) % / °C is found. Considering hints for a particle type dependency, electrons show (-0.17+-0.02) % / °C, whereas the temperature dependency seems stronger for a-particles, with (-0.35+-0.03) % / °C. A pulse shape analysis shows increased strength of a slow decay component at lower temperatures, pointing to reduced non-radiative triplet state de-excitations at lower temperatures.
