Review: Down Conversion Materials for Solid‐State Lighting

The wavelength down conversion approach to solid‐state lighting (SSL) uses down conversion materials to produce visible light when excited by near‐UV or blue emission from InGaN LEDs. This review discusses two classes of down conversion materials: phosphors and semiconductor quantum dots (QDs). Strong absorption of the excitation wavelength; high luminous efficacy of radiation, which enables white light with a high color rendering index and a low correlated color temperature; high quantum efficiency; and thermal and chemical stability are some of the criteria for down converters used in SSL. This review addresses the challenges in the development of down converters that satisfy all these criteria. We will discuss the advantages and disadvantages of several phosphor compositions for blue and near‐UV LEDs. The use of core/shell architectures to improve the photoluminescence and moisture resistance of phosphors is presented. QDs are another class of down conversion materials for near‐UV and blue LEDs. Strategies to improve the photostability and reduce the thermal quenching of QDs include strain‐graded core/shell interfaces and alloying. We discuss Cd‐containing II–VI QDs, and Cd‐free III–V and I–III–VI QDs and their potential for SSL applications. Finally, a description of different methods to integrate the phosphors and QDs with the LED is given.

“…Indeed, for wide practical application, large amounts of QDs are necessary and their physicochemical properties reached under labo ratory conditions must be reliably reproducible from synthesis to synthesis and stable for long time periods. In spite of the fact that the authors of some works reported the possibility of using the methods of InP QD synthesis for large scale production [69], the solu tion of this problem will likely take a long time and much effort.…”

Semiconductor colloidal quantum dots possessing unique spectral luminescent characteristics are of great interest for the development of novel materials and devices, which are promising to be used in var ious fields. However, the contemporary high quality quantum dots contain Cd, Pb, Hg, Se, and Te ions and are toxic, with this circumstance limiting their wide practical application. Therefore, the attention of researchers has recently been focused on A III B V semiconductor quantum dots-in particular, InP ones, which are markedly more environmentally safe. InP quantum dots have spectral characteristics similar to those of well studied CdSe quantum dots and can, in principle, replace the latter in many cases, especially, taking into account their more pronounced size effect caused by the narrow energy gap and the large Bohr radius of the exciton. Moreover, the stronger InP covalent bond than the ionic one in A II B VI semiconductors makes it possible to expect that they have a higher photostability and stability in active media. This work pre sents a review of the modern literature devoted to the synthesis and properties of colloidal indium phosphide quantum dots, which are very promising for use as substitutes of toxic cadmium based quantum dots.

RESUMO -Esse trabalho teve como objetivo o estudo do processo de geração de gotas em microfluídica para a produção de partículas poliméricas. A microfluídica é uma área que utiliza dispositivos capazes de processar pequenas quantidades de fluidos (gerando apenas regime laminar de escoamento), permitindo operações contínuas em uma única fase ou na formação de gotas (duas fases imiscíveis). O processo de geração de gotas em microfluídica é utilizado para a produção de partículas poliméricas. A partir do controle de vazões é possível modular a formação das gotas e também o tamanho das gotas formadas. Neste trabalho são discutidos os aspectos importantes na geração de gotas em sistemas microfluídicos e uma investigação do processo.
