Abstract

A mixture of biphenyl and tetracyanoethylene (TCNE), containing about 5% TCNE, is useful in thermochromic display devices and in laser-beam detector devices. The mixture is a red color at and above its melting point of 66 degrees C. At temperature below 66 Degrees C, the solid is a white color. This mixture can be placed in front of an IR (infrared) laser beam to show the beam pattern and position.
