Abstract
The present cluster-included material characterized by utilizing a porous host material for clusters having a pore larger in size than that of zeolite. The cluster-included material is obtained by forming a cluster in a pore of a mesoporous material having a pore size of 1.3 to 10 nm. When the mesoporous material is particularly a mesoporous material having a pore volume of not less than 60% of a total pore volume within a pore size range of -40 to +40% of a pore size which shows a maximum peak in a pore size distribution curve, a granular cluster having a uniform particle size or a fine-linear cluster having a uniform diameter is obtained. The cluster-included material performs the various quantum effects.
