Abstract: A spectrometer can include a plurality of semiconductor nanocrystals. Wavelength discrimination in the spectrometer can be achieved by differing light absorption and emission characteristics of different populations of semiconductor nanocrystals (e.g., populations of different materials, sizes or both). The spectrometer therefore can operate without the need for a grating, prism, or a similar optical component. A personal UV exposure tracking device can be portable, rugged, and inexpensive, and include a semiconductor nanocrystal spectrometer for recording a user's exposure to UV radiation. Other applications include a personal device (e.g. a smartphone) or a medical device where a semiconductor nanocrystal spectrometer is integrated.

Abstract translation: 光谱仪可以包括多个半导体纳米晶体。 可以通过不同的半导体纳米晶体群体（例如不同材料，大小或两者的群体）的不同的光吸收和发射特性来实现光谱仪中的波长鉴别。 因此，光谱仪可以在不需要光栅，棱镜或类似的光学部件的情况下操作。 个人UV曝光跟踪装置可以便携，坚固且便宜，并且包括用于记录用户暴露于紫外线辐射的半导体纳米晶体光谱仪。 其他应用包括集成了半导体纳米晶体光谱仪的个人设备（例如，智能电话机）或医疗设备。

Abstract: Un espectrómetro puede incluir una pluralidad de nanocristales semiconductores. La discriminación de longitud de onda en el espectrómetro puede lograrse al diferir las características de emisión y absorción de luz de diferentes poblaciones de nanocristales semiconductores (por ejemplo, poblaciones de diferentes materiales, tamaños o ambos). El espectrómetro por lo tanto puede operar sin la necesidad de una red, prisma, o un componente óptico similar. Un dispositivo de rastreo de exposición UV personal puede ser portátil, robusto, y barato, e incluye un espectrómetro de nanocristal semiconductor para registrar una exposición del usuario para la radiación UV. Otras aplicaciones incluyen un dispositivo personal (por ejemplo un teléfono inteligente) o un dispositivo médico donde un espectrómetro nanocristal semiconductor se integra.
