I want to know the answer to the following question:
In what decade were breakthroughs made that brought in the modern era of GaN-based optoelectronic devices?
All the background I'm provided with is that "This new development revolutionized LED lighting, making high-power blue light sources practical, leading to the development of technologies like BlueRay, as well as allowing the bright high resolution screens of modern tablets and phones.[citation needed]". Is that enough to answer the question?
Answer: no
