  • Laminated body for preparing wavelength conversion member and preparation method of wavelength conversion member
    Patent number: 11851370
    Abstract: The present invention relates to a laminate for preparing a wavelength converting member and a process for preparing a wavelength converting member. More particularly, the present invention relates to a laminate for preparing a wavelength converting member, which can be calcined at a temperature of 800° C. or lower, preferably 700° C. or lower and has a high light transmittance, a high refractive index, and a good shape upon the calcination, whereby it can be advantageously used for LEDs, and a process for efficiently preparing the wavelength converting member using a confining layer comprised of specific components.
    Type: Grant
