The correlation between photo-negative resistance characteristics and optical bistability characteristics of silicon photoelectronic negative resistance devices (SPNRDs) is analyzed.

According to the service environment of rifle, the outdoor exposure tests at Jiangjin and Wanning exposure sites and simulated environmental tests at laboratory were chosen to study the light fastness.

Moreover it has better light fastness than many brands of ink sold on the market.

A S-5766 light fastness molybdenum red pigment coated with inorganic compound has been prepared, which has reached 7～8 light fastness and heat-resistance up to 300℃ and good application properties.
