细菌视紫红质是一种光能存储与能量转换的生物膜蛋白质分子，在光作用下，能产生极为迅速的电荷分离和蛋白质电响应信号，这种光电信号不同于一般无机光电材料的光电响应特征。用电泳法在ＩＴＯ导电玻璃上沉积出定向细菌视紫红质薄膜，与铜电极构成夹细菌视紫红质薄膜和导电凝胶结构的光电探测器。实验研究了这种光电探测器在５３２ｎｍ波长、３０ｐｓ超短光脉冲作用下的光电响应信号。分析了产生这种光电响应的机理。 Bacteriorhodopsin is a biofilm protein molecule that stores and converts light energy. Under the action of light, bacteriorhodopsin can produce extremely rapid charge separation and signal response of proteins. This photoelectric signal is different from that of inorganic photoelectric materials feature. Electrophoretic deposition of oriented bacteriorhodopsin films on ITO conductive glass and photolithographic detector with bacteriochlorin and conductive gel structures with copper electrodes. The photodetector response of the photodetector at 532 nm and 30 ps ultra-short pulses was experimentally studied. The mechanism of producing this photoelectric response is analyzed.
