In this paper, it was found that luminescent bacteria could be killed by UV light and the bioluminescence intensity would be decreased. With the protection of nanooxide, the decrease of the bioluminescence could be supressed, therefore luminescent bacteria could be utilized to analyze and evaluate the UV‐shielding property of nanooxide. Vibrio‐qinghaiensis Q67, a kind of luminescent bacteria, was used here to study the influence of different kinds and concentrations of nanooxide on the luminescence intensity of bacteria, which were illuminated by UVA, UVB or UVC light, respectively. A method was established according to the relative value of the decrease of the luminescence intensity, which can be used to analyze and evaluate the UV‐shielding property of nanooxide against UVA, UVB or UVC light, respectively. It also provided an effective way to analyze and evaluate the UV‐shielding property of sunscreen for cosmetic and other industries.
