The samples viewed in ambient light vary from green-yellow to orange-red. These changes in color which have been noted by other workersi lo are attributed to the increasing size of the Cd-Se nano-ciystals. 

The Cd-Se nano-crystals stay suspended in solution and cannot be filtered out. The oleic acid acts as a surfactant, binding to the exterior of the crystal lattice and allowing for the 

The interior of the nanocrystal consists of uniform medium and the excited electron and hole pair. 

The potential energy outside the radius R is infinite—the radius R defines the confining boxmdary of the box.
