if there truly "is really no chance to grow or try out new technologies", then I recommend looking to change jobs. At first, it'll be scary and intimidating, but long term, it'll be worth it.
15 years ago, fresh out of college, I landed a job as an IT guy at a very small software company (~10 employees). After 7 years there, I had worked my way up to IT manager, and I also did some web dev work within the company. By year 5, I was starting to feel stale, and I had always wanted to do web dev full time. There wasn't any where for me to go, as the dev team was filled up, so by year 7, I was ready to start looking for a new job.
I found a new place that allowed me to do web dev full time, and I AM SO GLAD I made the switch. Since you're in the position of having a stable job, you can really take your time to find the right place for you.
Also, as others have pointed out, make sure you inquire within you company for any new opportunities, assuming you like the environment there, and if all else fails, decide whether or not leaving is the right things for you to do.
