Embodiment Construction

[0027] The present invention will be further explained in detail with reference to the following specific examples, which are illustrative rather than restrictive.

[0028] A CdS of that present invention x Se 1-x / ZnS quantum dot luminescent glass, which comprises the following raw materials in percentage by mole: SiO 2 60％～65％，Al 2 O 3 15％～25％，B 2 O 3 0.1％～5％，Na 2 O10％～20％，P 2 O 5 0.1％～5％，MgO0.1％～5％，SnO 0.1％～5％。

[0029] In the quantum dots, ZnO, CdS and Se are 5% ~ 15% of ZnO, 1% ~ 5% of CdS, 1% ~ 5% of Se, and CdS. x Se 1-x X in / Zn depends on the specific content of Se.

[0030] The above CdS are discussed below. x Se 1-x The function and specific content of each component in / ZnS quantum dot luminescent glass, the content unit is the mole percent content.

[0031] SiO 2 ：60％～65％。

[0032] SiO 2 It is an essential component for glass skeleton. When SiO in glass 2 When the concentration is low, the chemical durability of the obtained glass is low, but if SiO in the glass 2 If ...

Abstract

The invention relates to a quantum dot luminescent glass, and a preparation method and application thereof. Glass comprises 60-65% of SiO2, 15-25% of Al2O3, 0.1-5% of B2O3, 10-20% of Na2O, 0.1-5% of P2O5, 0.1-5% of MgO and 0.1-5% of SnO. A quantum dot comprises 5-15% of ZnO, 1-5% of CdS and 1-5% of Se. The preparation method comprises the following steps: preparing CdSxSe1x/ZnS powder from the quantum dot component; and uniformly mixing CdSxSe1x/ZnS powder with glass powder to obtain quantum dot luminescent glass powder, dissolving the quantum dot luminescent glass powder, casting to obtain aglass block, annealing, and cooling to room temperature to obtain the quantum dot luminescent glass.

Description

Technical field [0001] The invention belongs to the technical field of glass materials, in particular to quantum dot luminescent glass and a preparation method and application thereof. technical background [0002] Due to the quantum confinement effect and quantum size effect, semiconductor quantum dots have the characteristics of wide excitation spectrum, narrow half-peak width and adjustable wavelength, so nano-quantum dot materials have attracted extensive attention. Among them, nano quantum dot glass is a kind of luminescent glass with high transparency, chemical stability, thermal stability, short response time and high third-order nonlinear polarizability, which shows strong advantages in the practical application of photonic switches and devices and the improvement of existing optical devices. [0003] At present, semiconductor quantum dots are mainly composed of II ~ VI group elements (such as CdSe, CdTe, CdS, ZnS, etc.) and III ~ V group elements (such as lnP, lnAs, etc....
