Quantum dot is a semiconductor nanomaterial. The quantum dot includes a core constituted of InP, a first shell constituted of ZnSe, a second shell constituted of ZnS, and a gradient alloy intermediate layer. The core is wrapped by the first shell. The first shell is wrapped by the second shell, and the first and second shells have different materials. The gradient alloy intermediate layer is between the core and the first shell. The gradient layer includes an alloy constituted of In, P, Zn and Se. A content of the In and P gradually decreases from the core to the first shell. A content of the Zn and Se gradually increases from the core to the first shell. A particle size of the quantum dot is greater than or equal to 11 nm. The quantum dot is capable of emitting light upon excitation with a photoluminescence quantum yield equal to or more than 50%.

Semiconductor nanomaterial with high stability

Provided is a backlight module including a light source, a light guide plate, and a composite color-conversion layer. The light source emits a blue light. The light guide plate is optically coupled to the light source and the blue light transmits through the light guide plate. The composite color-conversion layer is disposed on the light guide plate. The composite color-conversion layer includes at least three different populations of quantum dots. The at least three different populations of quantum dots at least include a plurality of cyan quantum dots or a plurality of yellow quantum dots.

Backlight module with composite color-conversion optical material

Provided is a backlight unit including a light source, an encapsulation layer, and a green quantum dot film. The light source emits a blue light. The encapsulation layer encapsulates the light source. The encapsulation layer includes red phosphors and yellow phosphors. The green quantum dot film is disposed above the light source and the encapsulation layer. The blue light is transmitted through the encapsulation layer and the green quantum dot film to generate a white light. A display device including the said backlight unit is also provided.

Backlight unit with phosphors and quantum dots

Provided is a backlight module including a light guide plate, a light source and a light conversion layer. The light source is disposed at one side of the light guide plate. The light conversion layer is disposed over the light guide plate. The light conversion layer includes an optical composite material including 0.1 wt % to 15 wt % of a luminescent material and 85 wt % to 99.9 wt % of an acrylate-based polymer. The acrylate-based polymer is prepared from precursors including 5 wt % to 30 wt % of a surfactant having a thiol group.
