ABSTRACT:
A light absorbing matter is irradiated by light ranging from ultraviolet to infrared and absorbed light energy causes the matter to be raised to an excited energy state. The excited state is then locked by maintaining the temperature of the matter at a predetermined value. Light energy thus stored can be released for utilization by changing the value of the temperature from the predetermined value.
