Barrier free stable quantum dot film

A method of fabricating a barrier free quantum dot particles layer film, comprising:

• shielding quantum dot particles by at least one of a shielding method to form shielded quantum dot particles;
• and
• dispersing the shielded quantum dot particles in an adhesive comprising an acrylate adhesive, a silicone adhesive, a thermoplastic adhesive, or an UV cured adhesive to form a free standing quantum dot particles layer;
• wherein the shielded quantum dot particles are resistant to at least one of condition selected from the group consisting of high temperature, high humidity and water;
• wherein the quantum dot particles are shielded by at least one of a house shielding method, a ligand shielding method and a jacket shielding method;
• and
• wherein the house shielding method comprises encapsulating the quantum dot particles by swelling and shrinking of carrier polymers in a solvent;
• wherein the swelling is carried out by heating the carrier polymers;
• wherein the shrinking is carried out by cooling of the carrier polymers;
• wherein the encapsulating of quantum dot particles is controlled by sonicating and further evaporating excess solvent from the carrier polymers;
• wherein encapsulation efficiency of the carrier polymers is within a range of 5 to 20%;
• and wherein the house shielding method is characterized in providing moisture resistance property to the shielded quantum dot particles.
