Wavelength converting material and light emitting device
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.
