Nanomanufacturing - Key control characteristics - Part 3-1: Luminescent nanomaterials - Quantum efficiency
IEC 62607-3-1:2014 describes the procedures to be followed and precautions to be observed when performing reproducible measurements of the quantum efficiency of luminescent nanomaterials. Luminescent nanomaterials covered by this method include nano-objects such as quantum dots, nanophosphors, nanoparticles, nanofibers, nanocrystals, nanoplates, and structures containing these materials. The nanomaterials may be dispersed in either a liquid state (e.g., colloidal dispersion of quantum dots) or solid-state (e.g., nanofibers containing luminescent nanoparticles). This standard covers both relative measurements of liquid state luminescent nanomaterials and absolute measurements of both solid and liquid state nanomaterials. Key words: nanotechnology, nano, naloleds

L'IEC 62607-3-1:2014 décrit les procédures à suivre et les précautions à prendre pour effectuer des mesures reproductibles de rendement quantique sur les nanomatériaux luminescents. Les nanomatériaux luminescents concernés comprennent des nano-objets tels que les points quantiques, les nanoluminophores, les nanoparticules, les nanofibres, les nanocristaux et les nanofeuillets, ainsi que les structures dans lesquelles ils se trouvent. Les nanomatériaux peuvent être dans un état liquide (par exemple, dispersion colloïdale de points quantiques) ou solide (par exemple, nanofibres avec des nanoparticules luminescentes). Cette norme traite des mesures relatives réalisées sur les nanomatériaux luminescents à l'état liquide, ainsi que des mesures absolues réalisées sur les nanomatériaux à l'état solide et liquide. Mots clé: nanotechnologie, nano, nanoleds
Nanoproizvodnja - Ključne značilnosti - 3-1. del: Luminescenčni nanomateriali - Kvantna učinkovitost
Ta del standarda IEC 62607 opisuje postopke in previdnostne ukrepe, ki jih je treba upoštevati pri izvajanju ponovljivih meritev kvantne učinkovitosti luminesenčnih nanomaterialov. Luminesenčni nanomateriali, zajeti v tej metodi, vključujejo nanopredmete, kot so kvantne pike, nanofosforji, nanodelci, nanovlakna, nanokristali, nanoplošče in strukture s temi materiali. Nanomateriali so lahko razpršeni v tekočem stanju (npr. koloidna disperzija kvantnih pik) ali v trdnem stanju (npr. nanovlakna z luminesenčnimi nanodelci). Ta standard zajema relativne meritve luminesenčnih nanomaterialov v tekočem stanju ter absolutne meritve nanomaterialov v tekočem in trdnem stanju.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publicat
