The invention discloses a luminescent material having aggregation-induced emission, a method of making and an application thereof. The luminescent material herein has properties of aggregation-induced emission/aggregation-enhanced emission with the maximum absorption wavelength red shift to a visible area so that this type of luminescent material has potential applications in the field of biology. The luminescent material allows the formation of transfer of electric charges in a molecule and exhibits strong polar dependent emission in different solvents. The luminescent material does not emit due to strong dipoalr interaction in a molecule, but emits in a weak-polar environment with a cell. The luminescent material can serve as intracellular lipid droplet and intramicroalgae lipid droplet, and has the advantages of high selectivity, high emission stability and high biological compatibility.

A compression spring comprises a casing with a piston that is mounted on a piston rod being disposed for displacement therein. Two sectional casing chambers are provided in the casing, which are filled with pressure fluid and at least one of which is defined by the piston. A controllable first valve interconnects the sectional casing chambers in an open position and blocks the compression spring in a shut-off position. By way of an additional automatic valve between the sectional casing chambers, the compression spring, even when blocked, can be adjusted in the piston-rod push-out direction by a force being applied that is comparable to the push-out force that works in the push-out direction by the pressure of the pressure fluid. This provides for greater flexibility in use of the compression spring.
