  Scintillation detector is widely used for the particle detection in the field
of particle physics. Particle detectors containing fluorine-19
($^{19}\mathrm{F}$) are known to have advantages for Weakly Interacting Massive
Particles (WIMPs) dark matter search, especially for spin-dependent
interactions with WIMPs due to its spin structure. In this study, the
scintillation properties of carbontetrafluoride ($\mathrm{CF_{4}}$) gas at low
temperature was evaluated because its temperature dependence of light yield has
not been measured. We evaluated the light yield by cooling the gas from room
temperature (300K) to 263K. As a result, the light yield of $\mathrm{CF_{4}}$
was found to increase by $(41.0\pm4.0_{\rm stat.}\pm6.6_{\rm syst.})\%$ and the
energy resolution was also found to improve at low temperature.
