The present application relates to the field of biological medicine nanomaterials, and particularly relates to a kind of nanocomposite material and its preparation method and application.The preparation method of nanocomposite material provided by the present application, first, by a kind of room temperature fast, green method is synthesized hollow sodium bismuth fluoride carrier, and doping makes it have excellent upconversion luminescence performance, then using the excellent surface area of hollow sodium bismuth fluoride is successfully loaded photosensitizer MC540, clothing mould toxin, finally using DSPE-PEG-FA is modified, obtains nanocomposite material.It can effectively activate tumor cell endogenous calcium overload, induce tumor cell pyroptosis, realize the effect of efficient cancer treatment.

The application relates to the field of laser technology, in particular to a bismuth fluoride-based fiber laser amplifier, which comprises a pump source for emitting pump light, a dichroic mirror, a bismuth fluoride-based fiber, a coupling lens and a second collimating lens, the coupling lens is located on the first side of the bismuth fluoride-based fiber, the second collimating lens is located on the second side of the bismuth fluoride-based fiber, the pump light transmitted through the dichroic mirror is focused and coupled into the bismuth fluoride-based fiber through the coupling lens, a seed source for emitting seed light, the seed light is focused and coupled into the bismuth fluoride-based fiber through the coupling lens or the second collimating lens, and the seed light is output from the end of the bismuth fluoride-based fiber far away from the seed source after being amplified by the bismuth fluoride-based fiber. The application is at least beneficial to providing a fiber laser amplifier for the 4.0-4.3-micron wave band, which has good stability, a simple structure, low cost and high output power.
