We have analyzed the physical origins of the temperature gradient of the ordinary refractive index (dno / dT ) of liquid crystals. To achieve a large dno / dT , high birefringence and low clearing temperature play crucial roles. Based on these simple guidelines, we formulated two exemplary liquid crystal mixtures, designated as UCF-1 and UCF-2, and compared their physical properties with a commonly used commercial liquid crystal compound 5CB. The dno / dT of UCF-1 is ~4X higher than that of 5CB at room temperature.
