    Abstract: A light-emitting package structure includes a light transmissive adhesive layer, a substrate, and at least one light-emitting diode chip. The light transmissive adhesive layer includes a first surface and a second surface facing away from the first surface. The substrate is on the first surface of the light transmissive adhesive layer. The light-emitting diode chip is on the second surface of the light transmissive adhesive layer. The light transmissive adhesive layer has a first portion and a second portion on the second surface, the first portion surrounds the second portion, a vertical projection area of the second portion on the substrate at least entirely covers a vertical projection area of the light-emitting diode chip on the substrate, and a thickness of the second portion is smaller than or equal to a thickness of the first portion.

    Abstract: A wavelength converting material includes a luminous core and a first protective layer. The first protective layer covers the luminous core, and the first protective layer includes aluminum silicate. The aluminum silicate includes a plurality of silicon atoms, each of the silicon atoms is one of a zeroth configuration Q4(0Al), first configuration Q4(1Al), second configuration Q4(2Al), third configuration Q4(3Al), and fourth configuration Q4(4Al). The silicon atoms of the zeroth configuration do not connect with aluminum oxide group, and the silicon atoms of the first, second, third, and fourth configurations respectively connect with one, two, three, and four aluminum oxide group(s). A total number of the silicon atoms of the third configuration and the fourth configuration is larger than a total number of the silicon atoms of the zeroth configuration, the first configuration, and the second configuration.
