The effect of heating and subsequent cooling in air on the efficiency of optoelectric conversion in a nanographite (NG) film irradiated by nanosecond laser pulses of constant power has been studied. It is established that an increase in the temperature of heating in the T = 300–600 K interval leads to an approximately 30% decrease in the amplitude U of the optoelectric response signal. The further increase in the temperature is accompanied by a linear decrease in the U value. The U(T) dependence remains single-valued for NG films heated up to T = 530 K with the subsequent keeping at this temperature for no less that 10 h and cooling. Heating of the NG film above 640 K followed by exposure at this temperature leads to irreversible changes in the optoelectric conversion efficiency.
